The NCP372 is an overvoltage with a reverse leakage cancellation from lithium battery. The system is both positive and negative overvoltage protected up to +28 V and down to -28 V. The wall adapter is disconnected from the system if the input voltage exceeds the overvoltage (OVLO) or undervoltage (UVLO) thresholds. At powerup, the Vout turns on 30 ms after the Vin exceeds the undervoltage threshold. Thanks to the NCP372 using an internal NMOS, the system cost and the PCB area of the application board are minimized. The NCP372 provides a negative going flag (FLAG(BAR)) output which alerts the system that a fault has occurred. In addition, the device has ESD protected input (15 kV Air) when bypassed with a 1.0 µF or larger capacitor.
