Design Problems Engineers Face

Each Storage Rack has two Thermal Management Systems with 16 fansand two Temperature Sensors

Storage Rack by IBM

Traditional Approach and Challenges: To present the traditional approach and the challenges engineers will face when using it to realize the Market Vision. Ends with a one-sentence segue clearly stating the benefit of the Cypress solution.

Mission-critical systems cannot tolerate Thermal Management failuresWhen fans wear out or become blocked, or

When SMBus interfaces to the Host Processor go down

Fans create noise and consume significant power at maximum rpmThey must be driven at the minimum feasible rpm to minimize noise and power

They require a microcontroller running Thermal Algorithms to calculate the minimum feasible rpm

Every design requires difficult, time-consuming customization for:A different numbers of fans and different types of Temperature Sensors

Specialized analog ICs for each Temperature Sensor

Microcontroller-based firmware algorithms to correct and linearize sensor outputs

PSoC solves these problemsPSoC monitors the fan rpm for failures and supports redundant SMBus interfaces to the Host Processor

The Thermal Management Kit includes Thermal Algorithms in PSoC User Modules to minimize fan noise and power

One PSoC can control and monitor up to 8 fans and 24 Temperature Sensors

PSoC integrates the specialized analog ICs for each Temperature Sensor, including the ADC and IDAC ICs

PSoC Temperature Sensor User Modules provide firmware algorithms for accurate sensor conversion

PSoC User Module Wizards create customized Thermal Management configurations in minutes

PSoC creates a one-chip, customized, fail-safe Thermal Management solution
