Overcurrent and overtemperature fault reporting via OC output.","working_principle":"An internal charge pump generates gate voltage above the supply for the N-channel MOSFET power switch. When EN is high, the MOSFET turns on with controlled slew rate (4ms rise) to limit inrush current into the load capacitance. Current is sensed and limited to 2.2A. If overcurrent persists, thermal shutdown activates. The OC (open-drain) output asserts low on fault for host notification. UVLO prevents switch turn-on below 2.5V.","pin_description":"
