USB Positive Overvoltage Protection Controller with Internal PMOS FET and Overcurrent Protection

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 μF or larger capacitor.
