NCP361 Datasheet, PDF (1/12 Pages) ON Semiconductor – USB Positive Overvoltage Protection Controller with Internal PMOS FET and Overcurrent Protection
NCP361
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 mF or larger capacitor.
