ternal +5V supply can be used to supply external
circuits (See also AN495/0692). A signal is internally generatedto block the In signal, and prevent
activation of the output switch, as long as an abnormal condition is detected. The power-ontransition, 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 suchsignal
to ensure that a stable normal situation is present
when the signal disappears. The delay (of the disapperance 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 inductiveloads.
