Description

The TDE1707DFT 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). 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 over temperature and

the output overcurrent, concur to the generation of

such signal. A minimum delay of 25ms (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..
