DESIGN FEATURES

10 FPGAs Rev Up Motor Control System - Efficiency, Performance and Design FlexibilityElectric motors collectively consume a substantial portion of global electricity. According to the research firm IHS Technology, 96 percent of a motor’s lifetime costs are represented by pure electricity costs. Regulators have imposed more stringent energy standards for them, and manufacturers are scrutinizing their sizable contribution to equipment total cost of ownership (TCO). This has led to more complex motor control designs that use sensor-based and sensorless feedback loops and advanced algorithms for more precise control and greater motor efficiency.

12 Adding Intelligence to ControlThere are few applications addressed by integrated electronics that don’t require some modest form of power regulation, be that a simple current/voltage supply or a more sophisticated and optimised solution.

18 Commitment phobic? Not us

19 Kinetis MCU: A low power profileIn an embedded system, it is all about being more energy efficient across the application’s tasks, which can generally be broken into three phases: Initialization,Control and the Compute. To reduce power consumption the equation is simple, reduce the area underneath the curve; in essence, do more with less power and time.

Microchip Technology Inc., a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, has reclaimed the number-one posi-tion in worldwide 8-bit microcontroller (MCU) revenue, according toindustry analyst firm Gartner’s just-published 2014 rankings. This vali-dates Microchip’s unwavering commitment and innovation efforts for its8-bit PIC® microcontroller portfolio.While many MCU vendors have deemphasized their 8-bit offerings inrecent years, Microchip has continued to innovate across all of its 8-bit,16-bit and 32-bit product lines. And it continues to grow market share inall three areas, according to Gartner’s 2014 report. In the 16-bit MCUmarket, Microchip was the fastest-growing supplier among the top 10 in2014, growing at greater than 2X the rate of any of the other top 10 com-panies. Its 32-bit MCUs broke into the top 10 ranking of 32-bit MCU sup-pliers for the first time in 2014, based on 42.3% growth.

“We are pleased to report that Microchip has regained the #1 position for8-bit microcontrollers,” said Steve Sanghi, Microchip’s president and CEO.“Four years ago, it took the merger of three Japanese semiconductor giants -NEC, Hitachi and Mitsubishi in the form of Renesas - to knock us off the #1spot for 8-bit MCUs. We said at the time that we would work relentlessly togain market share and wrest back the #1 spot. Following their merger in2010, Renesas’ 8-bit MCU business was 41% larger than ours. In every yearsince 2010, we closed the gap, and in 2014 we regained our leadershipposition, finishing 10.5% higher than Renesas.”

8-bit PIC MCUs provide developers with an easy migration path from 6to 100 pins, with little or no code change required. This MCU portfoliooffers product families with varying levels of intelligent integration,including a host of Core Independent Peripherals, which require little tono CPU intervention, freeing the core to perform other application tasks.Also integrated are Intelligent Analog peripherals, including op amps,comparators, ADCs, DACs and CTMUs; Human Interface peripherals forLCD displays and mTouch® capacitive sensing; and Communications chan-nels for Ethernet, I2C™, SPI, USB, CAN and LIN (EUSARTs).

FPGAs Rev Up Motor Control System Efficiency, Performance and Design Flexibility

Motor designers also must support chang-ing industrial control standards and tech-nologies while providing critical system fea-tures that ensure safety, scalability and relia-bility. Meeting the twin goals of energy effi-ciency and enhanced system-level capabili-ties requires adequate processing power foralgorithm processing along with flexible andscalable system architectures. Non-volatile,secure and low-power flash-based systemon chip (SoC) FPGAs meet both challengesby delivering the necessary horsepowerwith a combination of both inherent andlayered security and reliability with protect-ed communications for Internet of Things(IoT) applications, and the ability to quicklyand easily scale from small-footprint to fea-ture-rich custom motor designs in a varietyof multi-axis or high-RPM applications.

The ChallengesWhile traditional designs use simple scalarcontrol, high-efficiency motors use Field-Oriented Control (FOC) across all torqueand speed ranges to significantly improveefficiency. Because it is current-controlled,FOC also optimizes power-inverter circuitryand the motor footprint depending on appli-cation requirements. It uses feedback loop-ing, with or without sensors, and sophisticat-ed algorithms to regulate key motor behav-iors including speed, position or angle,torque, current, and flux. While microcon-trollers (MCUs) and DSPs have traditionallybeen used for algorithm processing in single-and dual-axis designs, their processing capa-

bilities aren’t keeping up with growing multi-axis or high-rotation motor performancedemands. Adding to the challenge, motorcontrol efficiency is rarely the only concern,especially in connected factories wheretoday’s Internet of Things (IoT) environmentposes critical requirements for secure commu-nications – something that flash-based FPGAarchitectures are ideally suited to address. On the power electronics side of motorcontrol designs, there is also a migrationfrom insulated-gate bipolar transistor(IGBT) devices to silicon carbide (SiC)

power MOSFET devices. SiC solutions pro-vide higher bandgap for improved cooling(and therefore enable the use of smaller andcheaper heat sinks), greater thermal conduc-tivity to drive higher power densities, andhigher switching frequencies (greater than100kHz) which result in smaller magnetics atthe inverter stage. This, in turn, contributesto lowering the customer’s TCO. On the control side, higher switching frequen-cies are where DSPs and MCUs don’t fare well.Some DSPs may optimize a few channels forhigh-frequency switching, but they still lack

Electric motors collectively consume a substantial portion of global electricity. According tothe research firm IHS Technology, 96 percent of a motor’s lifetime costs are represented bypure electricity costs. Regulators have imposed more stringent energy standards for them,and manufacturers are scrutinizing their sizable contribution to equipment total cost ofownership (TCO). This has led to more complex motor control designs that use sensor-based and sensorless feedback loops and advanced algorithms for more precise controland greater motor efficiency.

DESIGN FPGAs


the ability to quickly adapt to changingrequirements, and to add more pulse widthmodulation (PWM) channels to control thepower electronics stage (in fact, this is oftenoffloaded to an FPGA). ASICs and ASSPs havethe same flexibility and scaling challenges.Flash-based FPGAs offer greater perform-ance than MCU/DSP-based solutions forhigh-speed, low-latency algorithm process-ing, while enabling the integration of addi-tional system functionality to furtherimprove TCO. Designers can use the flash-based FPGA to go beyond what MCUs/DSPscan support when scaling to higher switch-ing frequencies and more PWM channels tomatch the power electronics.Figure 1 shows a solution where a flash-based SoC FPGA with an ARM® Cortex-M3microcontroller can be used for motor con-trol and monitoring functions. The FPGAfabric is used for hardware acceleration ofmotor control functions to improve per-formance, and for design flexibility. Motorcontrol algorithms can be offloaded to theFPGA for faster parallel processing, withintelligent partitioning to ensure that allcommunications protocols in the microcon-troller subsystem can be handled with zeroimpact on the motor control algorithm cal-culations that are running in the FPGA.Capping off today’s FPGA solutions are mod-ular suites of plug-and-play IP blocks tailoredfor implementing all necessary mathematicalmotor models. Developers can determinewhich IP blocks to hardware-accelerate in theFPGA fabric so they can meet the full range ofalgorithm processing challenges. These solu-tions ensure low-power operation whileenabling developers to optimize their systemsfor reliability, safety and security using a sim-plified design process that speeds time tomarket while providing the flexibility and scal-ability to meet evolving needs.

Low-Power OperationFPGAs used for motor control design mustreduce both static and total power, especiallyat high frequencies and temperatures. FPGAsthat feature an embedded single-transistorflash cell offer an advantage as compared toalternatives that use a six-transistor SRAM cellthat must be configured from an externalROM during power-up. The latest flash-based FPGA solutions also use a comprehen-sive approach to minimizing power thatencompasses process technology, architec-ture and the design of configurable logic, aswell as embedded features including a hard-ened M3 MCU, 5G SERDES, DDR2/3, TSE,

DSP blocks, and special power modes. Thisapproach results in 50 percent lower totalpower and 10 percent lower static powerthan SRAM-based FPGA solutions.

Reliability, Safety and SecurityIn general, an FPGA is more reliable than amicrocontroller for implementing motorcontrol and network functions where deter-ministic timing is important. While there can

be milliseconds of timing variability in amicrocontroller, there are a few nanosec-onds or less in the FPGA.The best choice for security is flash-based,rather than SRAM-based FPGAs, becausethey store configuration information on-chipin non-volatile memory - the bit stream isnever exposed at start-up. They also provideimmunity to single event upsets (SEUs) thatchange configuration SRAM contents. Someflash-based FPGAs can also serve as root-of-trust devices with key storage capability toprotect hyperconnected industrial IoT sys-tems from cloning, tampering and other mali-cious attacks. These FPGAs address securityneeds with features like a physically unclon-able function (PUF) from which the PrivateKey in a Public/Private Key scheme can bederived for implementing M2M authentica-tion using Public Key Infrastructure (PKI).Other features include cryptographic acceler-ators, a random number generator, hardwarefirewalls to protect CPU/DSP cores, andDifferential Power Analysis (DPA) counter-measures that, together, allow security to belayered as needed throughout the system toprotect the hardware and data.

Design Simplicity through A ModularApproachModular and performance-oriented IPblock suites enable algorithms to be imple-mented with plug-and-play simplicity.Designs can easily be ported across multipleplatforms to speed time to market. All IPblocks are tested in simulations on actual

hardware to ensure precise torque output,and easily integrated to create task-specificmodules. Each block facilitates sharing ofcommon FPGA resources for the most effi-cient chip utilization (see Figure 2).The IP suite also includes all basic buildingblocks, including Clarke and Park transfor-mations, proportional integral (PI) con-trollers for control loop feedback, andspace vector PWM (SVPWM).

Flexibility and ScalabilityA modular IP suite also simplifies customiza-tion and scaling to support different combi-nations of multi-axis motors or high-RPMsolutions, while meeting evolving regionaltechnology standards. The more compactthe IP blocks (i.e., less than 10,000 logical ele-ments for the entire suite), the more head-room there is to support integration needs.An IP suite running on an FPGA can be scaledto drive from two brushless DC (BLDC)/step-per motor channels to a six-axis solution, or toextend motor performance beyond 70,000RPM, depending on requirements. One wayto scale to multi-axis FOC control is to time-division-multiplex each FOC loop within thedevice so each of the motors can be individu-ally controlled for different reference speedsand torque requirements. Everything is imple-mented in the FPGA fabric, leaving the micro-processor subsystem available for running acommunication protocol stack, providing thehuman-machine interface, or other tasks.Designers of electric motors must meet ener-gy mandates while ensuring systems can scaleand adapt. Flash-based SoC FPGAs providean increasingly attractive alternative to DSPs,MCUs, ASICs and ASSPs, combining the nec-essary processing horsepower with hardwareand software programmability plus broadoptions for accelerating and intelligently par-titioning functionality. Flash-based FPGAs addthe benefit of inherent security, and can serveas the root of trust for secure IoT communica-tions in the connected factory ￭www.microsemi.com

Adding Intelligence to Control

Risk & RewardA ‘low risk’ method of making powersmarter is to simply monitor the supplyusing an MCU and relay the parameters itmeasures to a back-system over some formof communication interface. This approachneeds minimal additional components anddesign effort; typically restricted to addingsome method for sensing the voltage, cur-rent and perhaps temperature. Monitoringother parameters, such as duty cycle or sup-ply frequency will allow more sophisticatedcontrol over power-specific features includ-ing voltage levels. There exist a number of Switched ModePower Supply ASSPs that offer a method of

modifying its functionality based on deci-sions made through measuring criticalparameters. It offers a simple way to increaseefficiency and is a task that can be handledby a wide range of microcontrollers; serialinterfaces effectively enables an MCU tomodify the functionality of the power supplybased on monitored parameters.

A further benefit of this approach is that thepower supply itself remains under the con-trol of the SMPS ASSP, which means thedesign team need not have any specificpower supply design knowledge beyondunderstanding the parameters available formodification, and the affect of that; the key

control theory remains the domain of theSMPS engineer. The next step along the implementationcurve — and one that offers potential costsavings — is to integrate the SMPS ASSP andMCU functionality in to a single device. It isincreasingly possible to achieve this in ahigh-performance MCU that is closely inte-grated to a fast sampling ADC; an approachthat affords a fully digital, all-softwareimplantation. Of course, this approachincurs the need for greater SMPS designexpertise, and the overall performance willbe related to how much processing powerthe MCU can deliver (often limited by sys-tem-level power requirements).

There are few applicationsaddressed by integrated elec-tronics that don’t require somemodest form of power regulation,be that a simple current/voltagesupply or a more sophisticatedand optimised solution. However,with an increased focus on effi-ciency at every level it is becom-ing common to extend the simpleto include some form of intelli-gence. Even a relatively unsophis-

ticated control algorithm can deliver performance benefits such as reduced power con-sumption, while with a little more effort any device can now include more advanced fea-tures such as maximum power tracking, refined battery charging, environmentally awaresettings and improved fault tolerance. This is a perfect scenario for low-cost microcontrollers, even the smallest device is nowpowerful enough to execute complex algorithms, while providing machine- and human-interfaces. The ability to accommodate some form of standardised communication inter-face, such as SMbus, LIN or Ethernet adds another level of value.

The Hybrid ApproachThe middle-ground between the twoscenarios described above is whatsome term the Hybrid Approach. Inthis case, a mixed-signal controllerwhich integrates the necessary ana-logue peripherals are, again, fullyintegrated and one such device is thePIC16F753. This device features anoperational amplifier, slope compen-sator, DAC, comparators and PWMcontroller in a single 14-pin MCU.

Each of the peripherals is programma-ble, allowing them to be combined ina variety of ways to create a largenumber of current mode power sup-plies. As they are software-controlled,configuration is dynamic, allowing itto adapt to changing power supplyconditions. This could see the deviceconfigured to operate as a hystereticcontroller with a simple firmwarefeed-forward regulator when instandby mode, but allowing the sup-ply to be quickly reconfigured forcontinuous current mode at a differ-ent operating frequency when morepower is demanded.

Because the supply’s control residesentirely within the MCU there is noneed for additional components tobe added later in the design cycle,which has the added benefit of bothsimplifying the design and loweringthe component count. Furthermore,as the solution is fully integrated thefirmware has total visibility of thepower supply parameters withoutsignificantly changing the designprocess, while the communicationsand intelligence interface can bedeveloped and verified by the powersupply engineering team.

A typical power supply based on thePIC16F753 is shown in Figure 1; mostimplementations are minor variationsof a common SMPS configuration. TheComplementary Output Generatorproduces a complementary outputwith a programmable deadband fromrising and falling inputs, while the CCPis configured to produce a program-mable frequency rising edge. Thecomparator, C1, produces the fallingedge when the current exceeds theoutput of the slope compensator.

Figure 1

Figure 2


DESIGN POWER

The CCP and C1 can be combined tocreate a maximum duty cycle, which isneeded by some topologies such asboost, flyback and SEPIC. The opera-tional amplifier, OPA, is used to providefeedback and compensation, while theDAC is used to provide the Op Amp’sreference (although the Fixed VoltageReference, FVR, can also be used if pro-grammable levels are not required). Theslope compensator can be reset by thecomparators or the COG, and it uses aprogrammable current sink to decay apre-charged capacitor (in this case, thecharge level is set by the OPA).

This is a relatively simple configurationand Figure 2 shows an example of itoperating as a boost supply regulatingcurrent in a LED string. The flowcharts inFigure 3a through 3c depict the levels ofintelligence that can be added once ithas been configured, allowing it target arange of applications.

ConclusionThe addition of intelligence to a powersupply has far-reaching benefits and caneither be achieved simply, by adding anMCU, or more comprehensively by usinga more capable, fully integrated solutionsuch as a high-performance dsPIC ormixed-signal MCU that integrates all theperformance and peripherals needed torealise a sophisticated single-chip SMPS.

However it is delivered, smart power hasthe potential to impact significantly onelectrical device operation and — moreimportantly — efficiency. With today’shighly capable, low-cost and fully inte-grated solutions, adding intelligence hasnever made more sense.

Maxim Integrated Products, Inc. addresses the need for higher through-put, smaller footprint, and lower power in industrial automation with theMAX14900E digital output switch.This eight-channel integrated circuit (IC) provides up to 70x faster speed,uses over 20% less power, and occupies 40% less space than existing solu-tions - all factors required in today’s faster, more localized, smaller endproducts. It is controlled by an eight-bit parallel interface, or via a stan-dard Serial Peripheral Interface (SPI) which is also used for configurationand monitoring. Multiple devices can be daisy-chained to support addi-tional I/O points via the single SPI interface, requiring only three isolatorsfor all channels to provide further savings in cost, board space, andpower. The serial mode includes cyclic redundancy checking (CRC) forassured data integrity, as well as global and per-channel diagnostics forremote system monitoring.Maxim offers both a complete reference design (MAXREFDES63#) as wellas an evaluation (EV) kit with special prototyping features. The credit-card-sized reference design integrates the MAX14900E, a microcon-troller, isolated I/O port, power supplies, UART, and USB port to simpli-fy incorporating the device into the final OEM product design, as well asprovide a means for quick evaluation.Key Advantages• Low power; high voltage: The eight digital channels require just 3mA

(maximum) of supply current; operates from a wide supply range of 10V to 36V and thus compatible with the 24V rail of many factory systems.

• High speed and drive: With an input-to-output propagation delay of 0.3usec (typical)/0.8usec (maximum), it can support fast switching rates of up to 100kHz in push pull configuration. On-resistance, a critical factor in static power dissipation is just 85mΩ (typical) and 165mΩ (maximum). It can drive current loads up to 850mA; outputs can be used in parallel to achieve even higher drive-current rating.

• High integration and space savings: Housed in a tiny, 48-pin 7 mm × 7 mm QFN package; uses significantly less board space.

• Data integrity: Offers per-channel and global diagnostics/monitoring via its SPI port, while users can access the I/O via an eight-bit parallel port. The serial link includes CRC error detection for enhanced data-link integrity.

So then, can a microcontroller product linebe immortal? Of course not, but manyengineers wish they could continue to purchase the same microcontroller in perpetuity. And while not eternity, theproof of this desire is exemplified by somecomponents of our MCU portfolio still selling in production for more than 25years. Clearly, engineers value supply assur-ance or steady production availability foran extended period. The reasons vary. For some, their products are expected tobe sold in the market unchanged for many,many years. For others, launching a productto market requires passing stringent certifi-cation and safety tests. Any changes later tothe system components would requirecostly re-certification.

For many, the adage “if it’s not broken,don’t fix it” applies. To address this need,Freescale created the Product Longevityprogram – making a broad range of devicesavailable up to 15 years.

Longevity, in this use of the word, refers tothe minimum lifetime commitment thatFreescale makes. Not to be confused withproduct reliability that indicates how long acomponent can be expected to operate ina system, longevity refers to the minimumduration from component introduction thatcustomers can expect to continue purchas-ing the component that is compatible withtheir system design. Understanding a component’s longevity is akey device selection criteria for a new sys-tem design.

So while not immortal, Freescale endeavorsto perpetuate the lifetime of our cus-tomer’s products through the long-termsupply of essential components.

Take a look at the Product Longevity site atwww.freescale.com/productlongevity andbrowse the list of devices that we plan toproduce (and the terms and conditions foreach) for at least 10 years, and in somecases 15 years.

So, there you have it: we’re not afraid ofcommitment.￭

DESIGN MCUs

Our ever-changing world of electronicsElectronics have made great strides since thefirst radio receiver/transmitter, a.k.a. the“walkie-talkie,” was introduced by Motorolain 1940. Since then, rapid advancementsand breakthrough innovations continue toimpact the way we interact with our world.We’re surrounded by embedded proces-sors and sensors in battery-operated mobiledevices like phones, tablets and other“smart” electronics. Ultimately, our world isdriven by embedded software that con-stantly collects and interprets data to makereal-time decisions. As consumers, weexpect extremely high performance fromour devices, and the growing expectation isthat each product release will bring morefunctionality, longer battery life, lowerprices, a better software experience, and aproduct safer for our environment. As thenumber of battery-operated devicesincreases, the importance placed on theembedded system to meet those require-ments is that much greater. If you’re a designengineer, you know this all too well, which iswhy you will be glad to hear that the KinetisMCUs are built around these requirements,especially power efficiency.

Kinetis microcontrollers are drivinglow power, even lowerIn the past, integrated circuit manufacturerswere pushed to deliver products withgreater performance and integration.Today, expectations have been raised.

Energy efficient appliances, electric vehicles,LED lighting and televisions started thetrend, but devices are getting much smarter:they are starting to make autonomous deci-sions without human intervention. Smarterintegration, performance efficiency and cre-ative solutions to solve the low power chal-lenge have become a top priority for theintegrated circuit manufacturers.The Kinetis MCUs have been built aroundreducing power consumption and will con-tinue to differentiate themselves from otherMCUs on the market.

Driving down power consumption,one device at a timeHere are just a few low power techniquesintegrated into the Kinetis portfolio, whichhelp to reduce power consumption.• Low power boot: Optimized for the

lowest power during the boot process by providing non-volatile control bits to set default chip clocking upon device power up

• Smart clocking: Scalable performance, as needed to meet application needs, through various clock sources and multipliersto set the clocks for peripherals or CPU, across all power modes

• Ultra-efficient processing: Real-time controland computation through the use of the world’s most efficient processor cores, the ARM® Cortex®-M, supplemented by Freescale proprietary hardware accelerators

• Flexible low power modes: Numerous power modes to power gate memories

and peripherals, allowing for dynamic and static power optimization that fits a wide range of use cases

• Autonomous, low power peripherals: Precious energy savings by enabling strategic peripherals to operate, and function with decision making capabilities,in power down modes, so that time spent sleeping can be extended

Kinetis MCUs can make a difference,and will be there to help when milliamps make a world of differenceToday’s embedded systems are not like thehardware-driven systems of our past. Theyare more complicated applications, withreal-time tasks that include harvesting datafrom sensors, computing algorithms andmaking informed decisions. These applica-tions require hardware that balances per-formance with power, but more so thanever, they require advanced software devel-opment. And as we move deeper into thisnew world, the need for power efficientdevices is growing. The innovation drivingthe Kinetis portfolio is fueled by the desireto design microcontrollers that consume lesspower, offer flexible power modes, smarterperipherals, and tightly integrated softwareand enablement solutions. To keep up onwhat the team has been working on, you cancheck out Freescale.com/lowpower. As newpower efficiency updates are made, we’llshare it here on the Embedded Beat ￭www.freescale.com

In an embedded system, it is all about being more energyefficient across the application’s tasks, which can generallybe broken into three phases: Initialization, Control andthe Compute. To reduce power consumption the equationis simple, reduce the area underneath the curve; inessence, do more with less power and time. This is achieved by being best-in-class in not just one ofthese phases, but in all three.

It’s been quite a while since I’ve updated you on the status ofFreescale’s sensor fusion efforts (One-stop-fusion-shopping atfreescale.com/sensorfusion). We haven’t been idle. We’ve addedsupport for FRDM-KL46Z boards and for Kinetis Design StudioIDE. The Sensor Fusion Toolkit for Windows has been expandedwith new and improved features. We’ve updated our user manu-al and vastly upgraded the content in the sensor fusion data sheet.

We’ve added a community support page atcommunity.freescale.com/community/sensors/sensorfusion. Butthe really big news is that we’ve taken the entire sensor fusionlibrary open source. It’s FREE. We got a lot of requests for lessrestrictive licensing terms and easier license checking in the code.We fixed both by eliminating all license checks, supplying theentire library in source form (no more node locked binaries) andswitching to a very flexible BSD license file. Source files mustretain the Freescale copyright, but you are free to use the codewith any set of sensors or MCUs, at no cost what-so-ever. This is Freescale’s way of encouraging broad adoption of sensorfusion-based techniques, regardless of who your supplier is.Which leads me to…

This week, at the MEMS User Group Executive Congress inScottsdale AZ, executive director Karen Lightman, announcedthe MIG Accelerated Innovation Community (AIC). The AIC isintended to facilitate sharing and adoption of algorithms for sen-sor fusion and analytics, shortening time to adoption, and (by

enabling re-use) allowing its users to focus on development ofnext generation functions. Freescale seeded the effort by con-tributing our sensor fusion library, documentation and source filesfor Windows and Android-based visualization tools. We’ll beexpanding these offerings in coming months.

Steve Whalley, MIG chief strategy officer, added that “AnalogDevices and NIST have already come on board, and PNI Sensor Corp.will contribute three algorithms: quaternion to heading pitch and roll;heart rate monitoring using PPG sensor; and step counting. We alsofully expect other MIG member companies to add further algorithmsto AIC over the next 30 to 60 days, providing a rich baseline algorithmcapability to assist developers with sensor fusion solutions.”

There have been a few sensor algorithm libraries on the web. Butthey were generally limited in ability or via license restrictions.Corporate acquisitions of Sensor Platforms, Movea and othersearlier this year have taken a number of commercial offerings outof the general market. The AIC makes professional level solutionsavailable for everyone else. Visit the MIG Open Source SensorFusion site to register and gain access to GitHub based code, doc-umentation and tools. In the spirit of full disclosure, my team andI authored much of the material currently on the site, so if youhave suggestions, please feel free to send them my way.

AIC also opens the door for companies to provide professionalsupport options, which Freescale plans start offering this month.The company will be making a bundled sensor fusion develop-ment kit (FRDM-SFUSION) available for purchase this month.The kit is offered at a suggested resale price of $170 USD andincludes Freescale’s FRDM-K64F, FRDM-FXS_MULTI-B boardspre-programmed with sensor fusion software compatible withour standard Sensor Fusion Toolbox for Windows.

Also available is a premium software development supportpackage that includes a private portal with up to 50 hours sup-port at a price of $10,000 USD. For more information, pleasevisit www.freescale.com/FRDM-SFUSION.

I’m really excited about taking our fusion library open source. I’malready seeing faster adoption, and I’m looking forward to othercontributors reviewing and adding to our work products, andadding their own. It’s a fun time to be in the sensor’s business ￭www.freescale.com

Toshiba Electronics Europe has launched a HardwareDevelopment Kit (HDK) and Software Development Kit (SDK)that together form a development platform for the TZ1000ApP LiteTM series. Suitable for wearable and IoT devices theTZ1000 series application processors enable activity levelmonitoring as well as taking a pulse and checking heart rate.

Toshiba is supplying IoT device developers with the HDK andSDK since May 7th, and is also conducting a trial campaign thatoffers a limited quantity of reference boards and the develop-ment environment free of charge. The TZ1000 series devices integrate a sensor, a processor, flashmemory, and a Bluetooth® Low Energy controller in a singlepackage. The series is designed to provide single-device solu-tions for measuring, processing, saving and communicating thedata required for wearable and IoT devices. The development environment includes a HDK embeddedwith the TZ1001MBG processor and a biometric sensor boardthat measures pulse waves and the heart’s electrical activities.The SDK includes driver software that controls each compo-nent incorporated in TZ1001MBG, middleware that measuresactivity and pulse waves, and application software that controlsthe overall system. The platform is supported by recommended developmenttools, including Keil® MDK-ARM and IAR EmbeddedWorkbench® for ARM. The kits will allow users to evaluate and develop software in anenvironment closer to their final products and to optimise use ofthe application processor for specific applications. The develop-ment environment will contribute to reduced design man-hoursand shorten time-to-market. Toshiba aims to further strengthen the TZ1000 series line-upwith the development of software algorithms to measure weakbiological signals, like pulse waves and the heart’s electrical activ-ities, as well as environmental data such as temperature andhumidity.TOSHIBA ELECTRONICS EUROPE www.toshiba.semicon-storage.com

Toshiba Launches Application ProcessorDevelopment Platforms for Wearable

and IoT DevicesEricsson has introduced a new DC/DC converter module based onthe company’s innovative and proprietary power topology known asHybrid Regulated Ratio (HRR) technology. The latest member of thePKM-NH series, the PKM4817LNH has been optimized for paralleloperation to power 2200W boards in extreme-data-demand appli-cations in the datacom industry.Offering 800W of power per unit, up to three PKM4817LNH mod-ules can be connected in parallel to achieve a total deliverable powerof 2200W. Parallel mode uses Droop Load Sharing, which means theoutput voltage has a typical droop characteristic, whereby the outputvoltage slightly decreases when the load is increasing, while stayingwithin system voltage limits.

Ericsson’s advanced HRR topology combines two power-controlmethods – voltage-regulation and ratio-regulation – and guaranteeshigh performance across the 45V to 60V input voltage ranges com-monly used in datacom systems that are powered by front-end recti-fiers. HRR offers excellent response to line and load transients andguarantees the output voltage will remain stable and immune fromvoltage deviations that are due to power disturbances on the systembus. This means it retains intermediate bus voltage integrity withinthe tolerance band required by power system architects.

Patrick Le Fèvre, Marketing and Communication Director, EricssonPower Modules, says: “The ability to operate these advanced high-power-density DC/DC converters in parallel meets the increasing needin the datacom industry for ever higher power with boards now reach-ing 2kW. The combination of Ericsson’s HRR technology and the abilityto easily parallel these new modules makes it possible to deliver the nec-essary high-density power required in extreme data traffic applications.”

Available in a quarter-brick format with a footprint of 57.9 x 36.8 x11.4mm, the PKM4817LNH operates with an input voltage range of45V to 60V and delivers an output voltage of 10V-11V at 80A withinthe operational system voltage between 51V and 60V. Below 50V, inregulated-ratio mode, the output voltage self-adjusts for optimal oper-ation and secures a stable voltage of 9.0V to 11V, even if the system busvoltage delivered via the front-end rectifier is operating abnormally.

Distec now runs embedded DisplayPort

Distec - leading German specialist for TFTflat screens and system solutions for indus-trial and multimedia applications – presentsthe autonomous TFT controller boardPrismaECO-eDP, the latest member of theproven Prisma family.

“In modern TFT displays with full HD resolu-tion, manufacturers are focusing more andmore on embedded DisplayPort (eDP) as aninput interface because compared to LVDSthe eDP standard enables higher data ratesand improved EMI performance at optimized

power consumption,” says Matthias Keller,COO Components at Distec. “This concernsparticularly the medium sizes since the eDPinterface is available in all current Intel andAMD chips, especially in the notebook /ultrabook area. Therefore eDP replaces LVDSofficially on PC platforms this year.” In addition to PRISMAeco-eDP the rangeof Distec’s intelligent eDP solutions includesthe small LVDS2eDP interface. Integrated inthe customer’s existing design, it simplyconverts the existing LVDS interface to eDP.Thus the customer may keep his controllersolution but still use one of the modern,sleek full-HD displays (eg. 12.5").

Cost-effective, space-saving andpowerful multimedia cardPrismaECO-eDP

PrismaECO-eDP features an HDMI and aDisplayPort input. It controls TFT displaysquickly and easily via dual-lane eDP inter-face and supports a resolution of currentlyWSXGA (1600×900) to WUXGA

(1920×1200). The brightness of the back-light can be controlled via Pulse WidthModulation (PWM) or analog voltage, butcan also be adjusted automatically to ambi-ent light conditions by using an optionalambient light sensor.A particular advantage of PrismaECO-eDPis the fact that it can be adjusted individual-ly to the requirements of the application. The exclusive configuration softwareChandlerRover enables for example portselection, timing, EDID programming andmany other settings. This is particularly use-ful for system integrators who can adjust thePrismaECO-eDP individually for each cus-tomer. Your configurations and OSD menusettings can be downloaded from the EEP-ROM of the controller board and easily betransferred to other boards. This allows fora quick serial production of precisely con-figured TFT controller boards for variousapplications. Thus, the PrismaECO-eDP isthe universal basis for custom projects withdifferent TFT displays.DISTEC www.distec.de

DESIGN SMART ANALOG IC

Smart Analog / sensortechnology ArticleThe world of industrial automation is entering the fourth industrial revolution. A paradigmshift in which rising awareness of energy efficiency, environmental concerns and regulations,qualitative productivity and operational health and safety, contribute to the continuedgrowth of machine to machine (M2M) technology. “Smart production” will become a normin the manufacturing engineering sector, where intelligent machine systems, through net-works interconnectivity will be capable of managing industrial production processes inde-pendently from human intervention, thereby making the “Internet of Things” a reality.

The M2M communications are made possi-ble with the use of industrial instrumenta-tion comprising of intelligent sensors capa-ble of capturing events (such as tempera-ture, location, consumption, levels, move-ment etc.) and relaying the data over a net-work (wireless, wired or hybrid) to an appli-cations (software program) that translatesthe captured event into meaningful informa-tion that can be analyzed and acted upon.Looking closer into the intelligent sensorsystem structure, the sensor (or transducers)are connected to one or more microcon-troller units (MCUs) that are at the core ofembedded system. The sensor’s outputgoes to the MCU’s input. The MCU process-es that incoming signal and executes controlfunctions accordingly. Depending on theapplication and situation, the sensor’s signalmight cause the MCU to execute tasks pre-defined by the user. The purpose of a sen-sor is to detect or measure, while the pur-pose of the MCU is to execute control inaccordance with the incoming information.When used together and properly inter-faced, these components function as "detectand control" electronics, enabling greaterfunctionality, convenience, safety and effi-ciency in embedded sensors systems.However the transducers’ output signal gen-erated may be very weak, into a noisy envi-

ronment, or delivered in a format incompat-ible with the one required by the MCU.Almost all MCUs have built-in analog-to-digital converter functions (ADCs or A/Ds)for translating analog sensor signals into adigital format. But those ADCs have restrict-ed capabilities; for instance, they generallyaccept only a limited range of input volt-ages. To boost these signals to the levelrequired by the MCU, or perform the nec-essary bridging (adaptation) function toimplement signal compatibility between thetransducer and the MCU, an Analog FrontEnd (AFE) is necessary. Furthermore, thetransducers’ output may contains too manyunwanted frequencies. This noise must beremoved before the analog signal is con-verted to digital. The AFE solution employslow-pass filter circuitry to block out high-frequency noise and/or high-pass filter cir-cuits to remove lower-frequency noise.Until recently, analog circuits were typicallydesigned manually by trial and error, whichrequired a considerable amount of time andexperience to complete a design, in somecases up to a year. Engineers today in thefast developing industry, are looking forsolutions enabling them to reduce thedevelopment time of their analog circuit,and release their products faster to the mar-ket. To answer the needs, a new type of AFE

design approach was needed, which is easyto apply, flexible, quick and effective.After carrying out large scale investigationinto analog circuit for sensors, the analogexperts in Renesas’ R& D labs have perfect-ed proprietary Smart Analog circuitry anddevelopment tools that can significantlyreduce the time and effort engineers mustexpend to develop new AFEs. Using theprogramming side from the MCU, SmartAnalog, makes use of the MCU to controlthe design of analog circuit, adjust its struc-ture and its characteristics into a sensorapplication.

Smart Analog circuits are designed at a com-puter screen using configurable designedoperational amplifier circuits that greatlyreduces the design time.As a sensor equipped system uses differenttype of transducers, for many different pur-poses, each of these sensors must have itsown analog circuit. Renesas Electronicstherefore designed a platform that enablesthe user to design the most basic analog cir-cuit to the more advanced Op-amp basedtopologies, by selecting and combiningappropriate types of Op-amp. The AFE Engineer is able to get his develop-ment projects up and running quickly andeasily, with the powerful GUI-based sensor

configuration software tool that enables “onthe fly”, i.e. while system is operating, config-uration and simulation of the analog front-end. The designer can easily, via simplemouse operation at the screen of a personalcomputer or work station, select the wiringand connections between the analog

blocks, change gain values or do offset tun-ing, and adjust other parameters. This great-ly simplifies sensors calibration or debug-ging and can reduce the overall design leadtime between 3 to 8 months significantlylowering development costs.

The Technology offers customizable multi-ple single-channel general-purpose ampblocks can be used to produce tailored I/V

trans-impedance converter/amplifiers, non-inverting amplifiers, inverting amplifiers, dif-ferential amplifiers, or summing amplifiers.The chip can be custom-configured toimplement a range of signal amplificationgains and it provides an adjustable span ofsignal voltage offsets (see Figure 1).

Additionally, the single-channel general-purpose amp in the AFE can be configuredto implement a single-channel high-imped-ance instrumentation amplifier. This type of differential amplifier is essentialfor interfacing to high-impedance sensors

such as piezoelectric types (see Figure 2).Other elements found in the Smart Analogblocks portfolio are single-channel amp

(with sync detection), single-channel low-pass filter with variable cutoff frequency,single-channel high-pass filter with variablecutoff frequency, high precision 16-bit or24-bit Delta-sigma A/D converter with built-in AUTOSCAN sequencer and programma-ble gain instrumentation amplification.

Compared to the classical discreteapproach, component count can bereduced by as much as a factor of ten, allow-ing for a much smaller overall footprint.Additionally, the power-on/off feature ofeach block of Smart Analog subsystem

yields significant savings in power consump-tion, in some cases as much as 20 percent.

The Smart Analog platform approach is par-ticularly versatile and convenient. It can beimplemented in two ways. One methodbased on a Smart Analog IC, which is a sin-gle-chip silicon die implementation of anAFE. System engineers insert it into theembedded control system to connect thetransducer to the MCU. The other oneapplies a Smart Analog MCU, a device thatcombines both AFE and MCU chips into asingle, integrated package. The Smart Analog MCU combines a SmartAnalog IC and an MCU into a space-saving,single-package device simplifying thedesign of sensor-based embedded controlsystems. Its internal MCU can be used tooptimize the sensor compatibility of the AFEchip, as well as to control that chip’s signal-interfacing characteristics. Due to thisunique combination of capabilities, theSmart Analog MCU is the only AFE solutionthat can handle the different outputs fromdiverse types of voltage, current and differ-

ential-output sensors. It provides enoughconnection terminals to accommodate allthe sensors typically needed, eliminatingthe traditional requirement to have a sepa-rate AFE circuit for each sensor. The SmartAnalog MCU helps shrink the circuit board,while simultaneously decreasing systemcomponent counts and costs.The reconfigurable characteristics of Smartanalog, means that Engineers now have afield programmable solution which can beused to plan sensor sensitivity loss overtime. Existing AFE design approaches makeit necessary during the manufacturingprocess to perform manual trimming tocompensate for variations in sensor charac-teristics. By contrast, a Smart Analog MCUautomates this process with the implemen-tation of automatic self-correction features.Thereby cutting system production andcommissioning costs, while increasing thesensor-based system’s operating lifetime Using the new Smart Analog solutions, engi-

neers can readily select the configurationand main features of the AFE they requireand, thereafter, change those selections asoften as necessary. This flexible design capa-bility significantly reduces the time that oth-erwise would be necessary for componentselection, board design, and parts procure-ment. Now the AFE portion of the system-development process can proceed muchfaster and more efficiently.Smart Analog technology represents a newinnovative platform for AFE design contribut-ing to the implementation of enhanced fea-tures into intelligent sensors, with the addedvalues of downsized systems, shorteneddesign cycle and lowered system cost. By sav-ing cost and time, the new customizable semi-conductor devices enable sensor manufac-turers, acting in the development of smarterfactories, to create products that otherwisemight be too expensive to produce or taketoo long to bring to market ￭www.renesas.com

ASIC Redesign – The Answer for Discontinued Parts

MAZeT GmbH, specialized in the develop-ment and custom production of embed-ded systems and optoelectronics, devised aredesign strategy for digital and mixed-sig-nal ASICs (application-specific integratedcircuits) as an answer to discontinued parts.With this move, MAZeT is guaranteeing thefuture operability of existing electronicsdevelopments.

“ASICs offer significant benefits compared tostandard ICs,” explains Dr. Fred Grunert,Managing Director of MAZeT. “An electronicsconcept geared towards a specific applica-tion contains precisely the required functionrange, which consequently reduces costs andresults in a compact solution. The electricalproperties are also improved. On the down-side, parts are only available for approx. six toeight years, and stock-keeping is limited to nomore than two years. To help companiesstruggling with these issues, MAZeT devel-oped the redesign solution. A redesignincreases availability and also makes it possi-ble to further optimize the ASIC.”

MAZeT is designing thenew ASIC to be compati-ble to the original ASICboth in terms of its func-tionality and connectionoptions, keeping follow-upto a minimum. The semi-conductor technology isselected based on thepremise that it is availableover the long haul. MAZeTthus demonstrates that anASIC redesign can be ahighly efficient alternative.

Digital and Mixed-Signal ASICsThere are purely digitaland mixed-signal ASICs. Asconcerns the redesign ofdigital ASICs, variousmethods are available,such as, for instance, mask-programmable and stan-dard-cell technology orreplacement with a pro-grammable logic module.

A mixed-signal ASIC contains digital mod-ules as well as an analog part of variablesize. The redesign effort is reduced byusing analog or digital IPs, a database that isas complete as possible, comprehensiveand detailed documentation of the ASIC,as well as a testing environment. Whenimplementing a concrete redesign orderfor a mixed-signal ASIC, MAZeT eliminatedthe weaknesses of the original ASIC: Forexample, the previous 0.6 μm CMOS tech-nology was replaced by 0.35 μm CMOStechnology, which will be available over thelong term. The entire pin assignment wasretained despite the improved redesign,allowing the existing printed circuit boards(PCB) to be still used.

Prerequisites for ASIC RedesignSuccessful ASIC redesign is subject to sev-eral conditions. The more of these are met,the lower the design risk, developmenttime, and redesign costs. The top priority isto provide a technical description includinga requirements specification, circuit plan,

high-level language description, netlist, anddata sheet in order to ensure functionalcompatibility. The testing vectors and envi-ronment are essential for delivering theproof of functionality needed for seriesproduction. What is also important is thedescription of the dynamic behavior as thelogic elements such as gates, flip-flops,memory etc. of a new semiconductor tech-nology often exhibit different delay timesand the analog transistors display a differ-ent electrical behavior, i.e., they representdifferent models. Other prerequisitesinclude the testing program for the circuittester, precise documentation of the ASIC’selectrical functions, the electrical characteri-zation of the input/output behavior, thesupply voltage concept, the ESD and EMCconcept, as well as the GDS2 data set.

DESIGN POWER MODULES

Design ProcedureStep 1Select the Soft Start CapacitorPlace a capacitor CSS between the SS and AGND pins to program thesoft-start, as shown in Figure 1. CSS can be calculated using the equation:

CSS = TSS × 10μA / 0.6V

Where: CSS = Soft start capacitor value in μFTSS = the soft start time of your choice

Step 2Select the DCM/CCM ModeThe DCM/CCM mode is based on the control signal EN/MODE as

shown in Figure 2.If EN/MODE = 2V-2.8V -> CCM modeIf EN/MODE ≥ 3.1V -> DCM/CCM mode

Step 3Program the On–TimeThe On–Time TON is programmed via the resistor RON shown inFigure 1 according to following equation:

RON = ((VOUT /fSW × η) - VIN × 25 × 10-9) / 2.85 × 10-10

Where:VOUT = Output VoltagefSW = Desired Switching frequencyη = Conversion EfficiencyVIN = Input Voltage

The proliferation of fully integrated power modules allows power engineers to quickly designa fully functional, stable, efficient DC/DC converter that meets all system requirements. Usingthe XR79115 from Exar as a design example, we shall demonstrate that the design can becompleted in a few minutes.Exar’s XR79115 is a synchronous step-down 15Amp fully integrated DC/DC converter thatrequires no control loop compensation because it employs a proprietary emulated currentmode Constant On-Time (COT) control scheme.

DESIGN POWER MODULES

Step 4Calculate the Over–Current Protection (OCP)If the load current exceeds the programmed over–current IOCP forfour consecutive switching cycles, then the power module will enterhiccup mode.The OCP current limit is calculated via the resistor RLIM shown inFigure 1 according to following equation:

RLIM = (IOCP × RDSON + 8mV) / ILIM

Where:RLIM = Resistor value for programming IOCP

IOCP = Over-current threshold to be programmedRDSON = 5mΩ = MOSFET rated on ResistanceProgram the Output Voltage

Step 5Program the Output VoltageUse an external voltage divider feedbacknetwork as shown in Figure 3 to programthe output voltage VOUT.

Where:R1 = R2 × ((VOUT / 0.6) -1)CFF = 1 / (2 × π × 80KHz × R1) RFF = 0.015 × R1

Step 6Select the Input CapacitorBefore starting this step, determine the acceptable input ripple volt-age VPP. Then calculate the minimum acceptable capacitor valueusing the formula below.

CIN(MIN) = 1 / (((VPP / IOUT) - ESR) × 4 × fSW)

Where:CIN (Min) = Minimum acceptable input capacitor valueVPP = Acceptable peak–to–peak input ripple voltageESR = Equivalent Series Resistor of the selected capacitorIOUT = Output load currentSelect a ceramic capacitor with a voltage rating that matches theinput voltage VIN with a 30% safety margin. The capacitor’s ripplecurrent rating must be greater than the RMS current.

IRMS = IOUT × √((VOUT / VIN) × (1 - (VOUT / VIN)))

Step 7Select the Output CapacitorsBefore starting this step, determine the maximum load current stepyou expect to encounter ΔIOUT, and the maximum voltage droopacceptable VDROOP. Typically the most important factor when deter-mining the output capacitor value is the acceptable droop voltageduring the transient response. Calculate the value of the output capacitor using the formula below.

COUT = (KC x ΔIOUT) / (VDROOP × fSW)

Where:KC = constant between 2 and 5ΔIOUT = Maximum current stepVDROOP = Maximum droop voltagefSW = Switching frequencySelect ceramic capacitors with a ripple current rating greater thanthe RMS current.

IRMS = (1 /(2 × √3)) × (VOUT × (VINMax-VOUT)) / (0.56 × 10-6 × fSW

× VINMax" )

Where:VOUT = Output VoltageVINMax = Maximum input voltagefSW = Switching frequency

DESIGN SENSORS

More for less

The water meter needed to measure thewater flow precisely with a battery-oper-ated, radio-controlled counter. The sensoris positioned behind a 6 mm-thick glasspanel in a housing made of stainless steelor aluminum, and the magnet is housed inan ethylene glycol antifreeze solution. Afurther sensor which detects the presenceor absence of a magnetic field is used fortamper evidence purposes. In addition,this can also function as a configurationswitch for determining the time for thecommunication of the measured values tothe remote readout device. The data aretransmitted via radio link to a remotereadout device, which collates them.

Mirakonta had previously used a reedswitch as a water flow meter, but this didn'talways deliver precise consumption values.A new sensor model would not only need todetermine more accurate values, but alsomeet the increasing demands on energyefficiency. For support with this task, themanufacturer turned to Rutronik.

Higher precision at lower energy consump-tion – those were the Spanish manufacturerMirakonta’s requirements when developinga new premium water meter. The focus of the project was on the sensorand Rutronik was on hand throughout tooffer the company support.

More efficient water metersthanks to new sensors


DESIGN SENSORS

Mirakonta has already been working closelywith the distributor for five years.

“In the past, we would have chosen a magnetsensor with low energy requirements for thistype of application,” explained ThomasKepcija, Product Sales Manager Sensors atRutronik. “This time, however, Mirakonta’srequirements on the energy consumptionwere so strict that those models simply could-n’t comply with them. As such, the new devel-opment from Honeywell Sensing and Controlcame at just the right time.”

The sensor specialist launched the indus-try’s first anisotropic magneto-resistive(AMR) nanopower sensor. With an energyconsumption in the nano range (360 nA)and high sensitivity of typically just 7 Gauss,it satisfies both criteria. Durable and ultrasensitive

Compared with other magnetic technologies,magneto-resistive sensor ICs offer a number ofadvantages: They are smaller, more durable, andmore reliable than reed switches, but still offer thesame sensitivity and are in the same price range. Assuch, they are ideal for battery-powered applica-tions, which function with a very low energy con-sumption and a large air gap, and for which it wasonly possible to use reed switches up until now.Compared with Hall-effect sensors, the increasedsensitivity of the nanopower sensor ICs of typical-ly 7 Gauss and maximum 11 Gauss makes it possi-ble to use them with an air gap twice as large.

“In addition, they take up less space and reducecosts, as smaller, weaker magnets can be used.Engineers are also afforded more design flexibility,as, thanks to the extreme sensitivity, they can workwith higher tolerances when it comes to the magnet-ic activation of the sensor,” summed up ThomasKepcija.

Rutronik provided Mirakonta with detailed techni-cal data and sent sample items within just a few daysfor testing of the new sensor. The tests showed: thenew sensor mastered all the challenges with flyingcolors. This positive result paved the way for devel-oping the new water meter.

Nicolas Roche, the product manager at Honeywell,is convinced that the nanopower range will giveMirakonta a new impulse, “In Mirakonta’s case, thisimproves the monitoring while reducing the energyconsumption and ultimately the costs. In addition, thelife span of the battery corresponds to that of the sen-sor and it was possible to eliminate the shortfalls ofolder technologies like the failure or gradual loss ofstability of the switches. All this makes the sensor agame-changing, sustainable product.” ￭

The switching points and switch-ing function can be programmed easily.

The 3-button operation ensures the simplesetting of the output signals and measure-ment parameters (scaling, damping, zeropoint stabilization, zero balance, characteris-tic curves conversion).

When a trolley bus reaches a road junction,wire-switches, installed on the overheadconductor cables, control its direction oftravel. Switches may be in the default“straight-through” position or in “turnout”

position. As a bus passes a switch in turnoutposition, a sensor mounted on the overheadcables detects the presence of the currentcollector. The control system then resets theswitch to the default position.

Power Integrations announced a new referencedesign (DER-479) demonstrating an industrialpower supply using the company’s LinkSwitch-4TM family of CV/CC primary-side regulated(PSR) switcher ICs with a 1200 V bipolar junctiontransistor (BJT). The design supports 440 VAC lineinputs and features three outputs which combineto provide up to 11 W of highly accurate constant-voltage DC power.

LinkSwitch-4 controllers feature an adaptive baseand emitter switched drive scheme to boostswitching performance and increase efficiency.The advanced switching technique is especiallybeneficial in high-voltage applications as it reducesslow turn-off switching losses and eliminates BJTfailures due to secondary breakdown, improvingthe reverse-bias safe operating area (RBSOA) andsystem reliability. Additionally, the LinkSwitch-4controller’s primary-side regulated sensingmethodology eliminates expensive and unreliableoptocouplers, replacing them in the feedbackloop with a simple transformer winding. Thedesign uses just 50 mW under no-load conditionswhile maintaining a fast transient response. The 65kHz operating frequency minimizes transformersize, reducing system cost and PCB footprint.LinkSwitch-4 devices also compensate for a num-ber of factors including: transformer inductancetolerances; input line voltage variations; cable volt-age drop; and external component temperaturevariations.

Comments Silvestro Fimiani, senior product mar-keting manager at Power Integrations: “Power supplies for high-voltage systems such asthree-phase meters and motor drives can be chal-lenging to develop – efficiency, reliability and com-ponent count often suffer in such designs. By pairingthe LinkSwitch-4 controller with a 1200 V BJT, thedesigns become very straightforward and extremelyreliable.”POWER INTEGRATIONSwww.power.com

Toshiba Electronics Europe has intro-duced a new four pin TO-247 MOS-FET package targeting power factorcontrol for high power Smart PowerStage (SPS). The new package isequipped with high speed DTMOS-Hchips with low QGD to optimiseswitching behaviour.In conventional three pin TO-247 packages, parasitic induc-tion at the source pin causesincreased losses with increasingswitching frequency. With thenew TO-247 4L package anadditional source signal termi-nal is separated as a ‘Kelvinsource’. By using this sourcepin, di/dt and switching efficiency canbe increased. Compared to a threepin solution, the switching loss E(on)will be reduced by the new four pinsolution by about 15%. The DTMOSIV-H chips are made using Toshiba’sDeep Trench technology that delivers

lower ON resistance (RDS(ON)) at highertemperatures, compared to conven-tional super junction MOSFETs. It alsooffers reduced turn-off switching loss-es (EOSS) than previous technologygenerations. The combination of

smaller increases in RDS(ON) at hightemperatures and reduced EOSS pro-vides higher efficiency for power sup-plies and assists designers in minimis-ing system size. TOSHIBA ELECTRONICS EUROPEwww.toshiba.semicon-storage.com

MAZeT GmbH presented new productsand innovative sensor solutions in thefields of LED light, process analytics, qual-ity control, and color measurement in hall12, booth 386 at the SENSOR+TEST tradefair, which was held from 19 to 21 May2015 in Nuremberg, Germany.

The JENCOLOR® sensors contain photodi-odes combined with structured interferencefilters. Typical features include high operat-ing frequency, parameters with long-termstability within a specified temperaturerange, low-tolerance spectral transmission,and operating temperatures above 100°C.The sensors can be delivered as electroniccomponents or as part of application-spe-cific modules and devices. User-specificsolutions for hardware, firmware, software,and support in the calibration of user-spe-cific solutions also form part of the MAZeTservice package.

Requirements for Opto-ASICs – highsensitivity and age-resistantPackaging is a priority with Opto-ASICs. Theproperties it offers need to ensure theseamless processing in the manufacturingprocess of an electronic module and guar-antee the functional features for the entirelifespan. More than 50,000 operating hoursare required for the LED light application inparticular. High sensitivity, bandwidth, ADC resolution,and spectral selectivity are parameters thatcan play an important role especially in theapplication areas of process instrumentationand color measurement. The many different functions offered by theserial interface of the sensor signal amplifierenable optimal adjustment to the variouscustomer applications and processes forrecording readings.MAZeT has been a successful provider ofOpto-ASICs and embedded systems forseveral years. At this year’s trade fair, thecompany will use selected demonstrators topresent the capabilities of its LED light colorcontrol and how to determine spectral foot-prints of fluids composed of highly variedsubstances.MAZeT now offers the option of adaptingexisting standard products to the customer’s

application requirements by varying thespectral filter characteristics. These applica-tion-specific hyperspectral sensors offer thechance to explore new application areaswith cost-efficient, spectrally resolved opti-cal point sensors.

MAZeT provides solutions for line and matrixsensors with low complexity for spatiallyresolved optical sensors. These can be adjust-ed according to the customer’s requirementson request. The pixels can be combined withspectral filters if this function is required.At the trade fair, Opto-ASIC specialists from

MAZeT have advised interested customers onthe options in terms of technology, costs, anddevelopment time for their project on site.

Spectral data gains increasing importanceMAZeT offers hyperspectral sensors as stan-dard electronic components for the VISrange. A development kit is available in sev-eral different versions to support the cus-tomer. The data logging and evaluation soft-ware ensures rapid start-up of the sensorevaluation board and allows the customer toefficiently work on the solution for hisdefined task.The JENCOLOR® hyperspectral sensors areparticularly well suited to calculating thespectral footprint of transparent fluids witha continuous spectrum.

A further application scenario is in thearea of quality assurance and processinstrumentation.

It is possible to quickly expand the analyz-able spectral range in the NIR range (< 1000nm) and the UV range (> 250 nm) at anytime (for example, by adjusting the filtercharacteristics) and at low cost.

The electronic sensor components arealways delivered in the familiar design of theMMCS6CS hyperspectral sensor.

Customized signal analysisMAZeT also offers integrated signal process-ing ASSPs to complement its JENCOLOR®sensors. The MAZeT product line rangesfrom programmable, multi-channel transim-pedance amplifiers, right through to signalamplifiers with an I2C or SPI port.

A key functional component of the new gen-eration of signal amplifiers are the analog-to-digital converters, which are tailored to therequirements of the JENCOLOR® sensors.These signal amplifiers need to reliably cap-ture photocurrents from multiple powersources at the same time and convert them inhigh resolution. MAZeT provides a measure-ment value resolution for this of up to 20 Bit(20 fA/LSB to 5 nA/LSB). The absolutedynamic is greater than 1:1,000,000.

These new models provide the high performance of fluxgate technol-ogy based transducers across the extended temperature range, deliv-ering extremely high accuracy with linearity over temperature rangebetter than 12 ppm, and a low offset over temperature rangebetween 36 to 400 ppm (according to the model). The fast responsetime to di/dt step changes is less than 0.5 μs, due to a precise and con-sistent winding process.The IT xx5 series has been designed to operate from a bipolar +/-15V DC power supply and will accommodate round primary conduc-tors of 26 and 30 mm diameter, depending upon the model used. Inaddition to their normal current output, the transducers offer anadditional output indicating the transducer state (low or high outputlevels) and an external LED showing normal operation.The new IT xx5 range is also fully compatible with the previous LEMIT range, fitting the same footprint. These transducers can be easilyretrofitted into old installations while maintaining the various com-pact sizes for each current range and a variety of panel mountingtopologies (flat or vertical), without compromising the high insulationlevel provided between the primary and measurement circuits.The transducers are CE marked and are covered by LEM’s five-yearwarranty.
