NCP349

Positive Overvoltage

Protection Controller with

Internal Low R_ONNMOS FET

The NCP349 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.

input voltage exceeds the overvoltage threshold (OVLO) or

undervoltage threshold (UVLO).

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

the V exceeds the undervoltage threshold.

The NCP349 provides a negative going flag (FLAG) output, which

alerts the system that a fault has occurred.

= Pb−Free Package

In addition, the device has ESD−protected input (15 kV Air) when

bypassed with a 1.0 mF or larger capacitor.
