NCP372 - Positive and Negative Overvoltage Protection Controller
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
NCP372 Positive and Negative Overvoltage Protection Controller with Internal Low Ron NMOS FETs and Status FLAG The NCP372 is able to disconnect systems from its output pin when wrong operating conditions are detected at it’s input.
The system is both positive and negative overvoltage protected up to ±28 V.
This device uses internal NMOS, and therefore, no external device is necessary, reducing the system cost and the PCB area of the application board.
The NCP372 is able to instantaneously disco
