control of the slow-start circuit, heating up due to the fault,
and then shutting down upon reaching the thermal
shutdown trip point.
Power Good (PWRGD)
The power good circuit monitors for under voltage
conditions on VSENSE. If the voltage on VSENSE falls
10% below the reference voltage, the open-drain PWRGD
output is pulled low. PWRGD is also pulled low if VIN is
less than the UVLO threshold, or SS/ENA is low, or
thermal shutdown is asserted. When VIN = UVLO
threshold, SS/ENA = enable threshold, and VSENSE >
90% of V

, the open drain output of the PWRGD pin is
high. A hysteresis voltage equal to 3% of V

falling edge deglitch circuit prevent tripping of the power
