NCP361SNT1G.PDF

The NCP361 disconnects systems at its output when wrong VBUS

operating conditions are detected at its input. The system is positive

over−voltage protected up to +20 V.

Thanks to an integrated PMOS FET, no external device is

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

application board.

The NCP361 is able to instantaneously disconnect the output from

the input if the input voltage exceeds the overvoltage threshold

(5.675 V). Thanks to an overcurrent protection, the integrated PMOS

is turning off when the charge current exceeds current limit (see

options in ordering information).

The NCP361 provides a negative going flag (FLAG) output, which

alerts the system that voltage, current or overtemperature faults have

occurred.

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

bypassed with a 1 F or larger capacitor.
