NCP360
USB Positive Overvoltage
Protection Controller with
Internal PMOS FET and
Status FLAG
NCP360 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
application board.
NCP360 is able to instantaneously disconnect the output from the
input if the input voltage exceeds the overvoltage threshold (OVLO).
NCP360 provides a negative going flag (FLAG) output, which
alerts the system that a fault has occurred.
In addition, the device has ESD-protected input (15ĂkV Air) when
bypassed with a 1ĂmF or larger capacitor.
