NPS4053GH-Q100Z

When the output load exceeds the current limit threshold or a short circuit occurs, the switch limits the output current to a constant level via constant-current mode. An internal voltage comparator disables the load switch when the output voltage exceeds the input voltage, protecting devices on the switch input side. The FLG pin is an active-low output that indicates overcurrent, overtemperature, and reverse voltage conditions.
