condition, the device cycles continuously; starting up by
control of the soft-start circuit, heating up due to the fault,
and then shutting down upon reaching the thermal
shutdown point.
Power Good (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
thermal shutdown is asserted. 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.
