ternal +5V supply can be used to supply external
circuits (See also AN495/0692). A signal is internallygeneratedto 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 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 such signal
to ensure that a stable normal situationis present
when thesignal 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 resistiveor inductiveloads.
