NCP370 Datasheet - ON Semiconductor

NCP370 Positive and Negative Overvoltage Protection

Pin Name Type Description 1, 2 IN POWER Input voltage pins. These pins are connected to the power supply. A 1 mF low ESR ceramic capacitor, or larger, must be connected between these pins and GND. The two IN pins must be hardwired to common supply. 3 GND POWER Main Ground 4 RES INPUT Reserve.

NCP370 Positive and Negative Overvoltage Protection with Internal Low RON N-MOSFETs and Reverse Charge Control Pin http://onsemi.com 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.
