NCP373MU04TXG

Positive and Negative Overvoltage Protection with Internal Low RON N-MOSFETs and Reverse Charge Control Pin
The NCP370 is an overvoltage, overcurrent and reverse control device. Two main modes are available by setting logic pins. First mode is Direct Mode from Wall−Adapter to the system. In this mode the system is both positive and negative over−voltage protected up to +28 V and down to −28 V.
The wall adapter (or AC/DC charger) is disconnected from the system if the input voltage exceeds the overvoltage (OVLO) or undervoltage (UVLO) thresholds. At power up, the Vout turns on 30 ms after the Vin exceeds the undervoltage threshold.In addition, the device has ESD−protected input (15 kV Air) when bypassed with a 1 μF or larger capacitor.
