NCP372

Positive and Negative

Overvoltage Protection

Controller with Internal

Low R_onNMOS 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.

MARKING

NCAI

372

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 disconnect the output from

the input, due to integrated Low R Power NMOS, if the input

voltage exceeds the overvoltage threshold (OVLO) or undervoltage

threshold (UVLO).

At powerup (EN pin = low level), the V turns on 30 ms after the

out

exceeds the undervoltage threshold.

(Note: Microdot may be in either location)

The NCP372 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.
