DESCRIPTION
The TDE1707 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 VS (Low side Mode)
Especially dedicated to proximity detectors, its in-

ternal +5V supply can be used to supply external
circuits (See also AN495/0692). A signal is inter-
nally generated to block the In signal, and prevent
activation of the output switch, as long as an ab-
normal condition is detected. The power-on tran-
sition, 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 dis-
apperance of the block signal; no delay at its on
set) can be further increased connecting a ca-
pacitor between pin3 and ground. It can drive re-
sistive or inductive loads.
