DESCRIPTION
The TDE1707BFP is a 0.5A Integrated Power Switch with up to 48V Power supply capability.
Two output configurations are possible:
- Load to Gnd. (High Side Mode)
- Load to V Especially dedicated to proximity detectors, its in-

ORDERING NUMBER: TDE1707BFP
ternal +5V supply can be used to supply external circuits (See also AN495/0692). A signal is inter­nally generated to block the In signal, and prevent activation of the output switch, as long as an ab­normal condition is detected. The power-on tran­sition, as well as the chip overtemperature and the output overcurrent, concurr to the generation of such signal. A minimum delay of 25µs (Typ. value) is added to the trailing edge of such signal to ensure that a stable normal situation is present when the signal disappears. The delay (of the dis­apperance of the block signal; no delay at its on set) can be further increased connecting a ca­pacitor between pin3 and ground. It can drive re­sistive or inductive loads.

Application Circuit, when the voltage on pin 8 (the output) differs from V
less than 1.5V, the output
CC
is sensed in "OFF" state and the LED driver is disabled. If instead pin 8 differs from V
more than 3V (the
CC
output comparator threshold value plus the drop voltage on the LED), then the output is sensed "ON" and the driver will force the current on the LED.
