Description
The TDE1708DFT is an integrated power switch
with up to 48 V 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
internal +5 V supply can be used to supply
external circuits (See also AN495).
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 over
temperature and the output overcurrent, concur to
the generation of such signal. A minimum delay of
25 ms (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 disappearance 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.
