NCP361
USB Positive Overvoltage
Protection Controller with
Internal PMOS FET and
Overcurrent Protection
NCP361 is able to disconnect the systems from its output pin in
case wrong VBUS operating conditions is detected. The system is
positive over-voltage protected up to +20ĂV.
Thanks to this device using internal PMOS FET, no external
device is necessary, reducing the system cost and the PCB area of the
www.DataSheet4aUp.pcloimcation board.
NCP361 is able to instantaneously disconnect the output from the
input if the input voltage exceeds the overvoltage threshold
(5.675ĂV). Thanks to an overcurrent protection, the integrated PMOS
is turning off when the charge current exceeds current limit (see
options in ordering information).
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 (15ĂkV Air) when
bypassed with a 1ĂmF or larger capacitor.
