(1) Shorted-circuit timer starts after POR timer. If V
DS
drops more than (V
PP
-V
NN
) after t
SC
then a shorted-circuit condition exists.
(2) If the output current is in an overload condition then the output immediately goes to current limit and starts the over-current timer. If I
OUT
does not drop back
below I
LIMIT
before the timer expires then an over current condition exists. The timer is immediately reset when a fault is cleared.
(3) Time for fast return to limit circuit to react.
(4) Guaranteed by design.
