Chipsmall Limited consists of a professional team with an average of over 10 year of expertise in the distribution
of electronic components. Based in Hongkong, we have already established firm and mutual-benefit business
relationships with customers from,Europe,America and south Asia,supplying obsolete and hard-to-find components
to meet their specific needs.
With the principle of “Quality Parts,Customers Priority,Honest Operation,and Considerate Service”,our business
mainly focus on the distribution of electronic components. Line cards we deal with include
Microchip,ALPS,ROHM,Xilinx,Pulse,ON,Everlight and Freescale. Main products comprise
IC,Modules,Potentiometer,IC Socket,Relay,Connector.Our parts cover such applications as commercial,industrial,
and automotives areas.
We are looking forward to setting up business relationship with you and hope to provide you with the best service
and solution. Let us make a better world for our industry!
The TDE1707BFP is a 0.5A Integrated PowerSwitch with up to 48V Power supply capability.
Two output configurations are possible:
- Load to Gnd. (High Side Mode)- Load to VS (Low side Mode)
Especially dedicated to proximity detectors, its in-
ternal +5V supply can be used to supply externalcircuits (See also AN495/0692). A signal is inter-nally generated to block the In signal, and preventactivation of the output switch, as long as an ab-normal condition is detected. The power-on tran-sition, as well as the chip overtemperature andthe output overcurrent, concurr to the generationof such signal. A minimum delay of 25µs (Typ.value) is added to the trailing edge of such signalto ensure that a stable normal situation is presentwhen the signal disappears. The delay (of the dis-apperance of the block signal; no delay at its onset) can be further increased connecting a ca-pacitor between pin3 and ground. It can drive re-sistive or inductive loads.
This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice.

The LED driver tells the output status.It can source or sink current (Iold typ = 3mA), ac-cording to the output configuration chosen.The thresholds, represented by the output com-parator in the Block Diagram, are set at about1.5V - 2V.For instance, in the High Side Load case of the
Application Circuit, when the voltage on pin 8 (theoutput) differs from VCC less than 1.5V, the outputis sensed in "OFF" state and the LED driver isdisabled.If instead pin 8 differs from VCC more than 3V (theoutput comparator threshold value plus the dropvoltage on the LED), then the output is sensed"ON" and the driver will force the current on theLED.
