NCV361
NCP361, NCV361
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
overvoltage 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 ESDprotected input (15 kV Air) when
bypassed with a 1 mF or larger capacitor.

PIN FUNCTION DESCRIPTION (UDFN Package)
Pin No. Name
Type
Description
1 EN INPUT Enable Pin. The device enters in shutdown mode when this pin is tied to a high level. In this case the
output is disconnected from the input. To allow normal functionality, the EN pin shall be connected to
GND or to a I/O pin. This pin does not have an impact on the fault detection.
2 GND POWER Ground
3 IN POWER Input Voltage Pin. This pin is connected to the VBUS. A 1 mF low ESR ceramic capacitor, or larger,
must be connected between this pin and GND.
4, 5 OUT OUTPUT Output Voltage Pin. The output is disconnected from the VBUS power supply when the input voltage is
above OVLO threshold or below UVLO threshold. A 1 mF capacitor must be connected to these pins.
The two OUT pins must be hardwired to common supply.
6 FLAG OUTPUT Fault Indication Pin. This pin allows an external system to detect a fault on VBUS pin. The FLAG pin
goes low when input voltage exceeds OVLO threshold. Since the FLAG pin is open drain functionality,
an external pull up resistor to VCC must be added.
