NCP349

Positive Overvoltage

Protection Controller with

Internal Low R_ONNMOS FET

The NCP349 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.

The NCP349 is able to instantaneously disconnect the output from

the input, due to integrated Low R Power NMOS (65 mW), if the

input voltage exceeds the overvoltage threshold (OVLO) or falls

below the undervoltage threshold (UVLO).

the V exceeds the undervoltage threshold.

The NCP349 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.
