to the fault condition, and then shutting down on reaching
the thermal shutdown trip-point. This sequence repeats
until the fault condition is removed.
POWERGOOD (PWRGD)
The power-good circuit monitors for under-voltage
conditions on VSENSE. If the voltage on VSENSE is 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 a
thermal shutdown occurs. When VIN ≥ UVLO threshold,
SS/ENA ≥ enable threshold, and VSENSE > 90% of Vref,
the open-drain output of the PWRGD pin is high. A
hysteresis voltage equal to 3% of Vref and a 35-s
falling-edge deglitch circuit prevent tripping of the
power-good comparator due to high-frequency noise.
