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

INTELLIGENT POWER SWITCH

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 25 s (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.
