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-

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.
