Intelligent power switch
DFN (4x4)
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 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..
