8.3 Power-OK
The AS1363 features a power-ok indicator that asserts when the output voltage falls out of regulation. The open-drain POK output goes low
when output voltage at OUT falls 6% below its nominal value. A 100k ? pull-up resistor from POK to a (typically OUT) provides a logic control
signal.
POK can be used as a power-on-reset (POR) signal to a microcontroller or can drive an external LED to indicate a power failure condition.
Note: POK is low during shutdown.
8.4 Current Limit
The AS1363 features current limiting circuitry that monitors the pass transistor, limiting short-circuit output current to 0.8A (typ). The circuitry of
the AS1363 allows that the output can be shorted to ground for an indefinite period of time without damaging the device.
8.5 Thermal Overload Protection
Integrated thermal overload protection limits the total power dissipation in the AS1363. When the junction temperature (T J ) exceeds +170oC
typically, the pass transistor is turned off. Normal operation is continued when T J drops approximately 20oC.
Note: Regardless of the hysteresis, continuous short-circuit condition will result in a pulsed output.
