NCP348AE, NCP348, Positive Overvoltage Protection Controller
Pin No.
Symbol Function Description 1 IN POWER Input Voltage Pin.
4 This pin is connected to the power supply.
5 The device system core is supplied by this input.
A 1 mF low ESR ceramic capacitor, or larger, must be connected between this pin and GND.
The three IN pins must be hardwired to common
NCP348, NCP348AE Positive Overvoltage Protection Controller with Internal Low RON NMOS FET and Status FLAG The NCP348 is able to disconnect the systems from its output pin in case wrong input operating conditions are detected.
The system is positive overvoltage protected up to +28 V.
Due to this device using internal NMOS, no external device is necessary, reducing the system cost and the PCB area of the application board.
The NCP348 is able to instantaneously disconnect the output from the inpu
