NCP391

Positive Overvoltage

Protection Controller with

Internal Low R_ONNMOS FET

The NCP391 is able to disconnect the systems from its output pin

when wrong input operating conditions are detected. The system is

positive overvoltage protected up to +28 V.

This device uses an internal NMOS and therefore, no external

device is necessary, reducing the system cost and the PCB area of the

application board.

Power NMOS, if the input

voltage exceeds the overvoltage threshold (OVLO) or falls below the

undervoltage threshold (UVLO).

At powerup (EN pin = low level), the V turns on t time after

out

the V exceeds the undervoltage threshold.

The NCP391 provides a negative going flag (FLAG) 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 mF or larger capacitor.
