NCP360: Overvoltage Protection Circuit, USB Positive, with Internal PMOS FET and Status Flag

NCP360 is able to disconnect the system from its output pin in case wrong VBUS operating conditions are detected. The system is positive overvoltage protected up to +20 V. Thanks to the integrated 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 (15 kV Air) when bypassed with a 1.0 µF or larger capacitor.

Benefits

When wall adapter or AC-DC overvoltage appears, the internal pass element is turned off very fast in order to protect the downstream system. The current consumption is around 25 µA although the very fast turn off capability.
No external device is necessary.
Typical OVLO is set to 5.675 V. Additional threshold can be manufactured. Please contact your ON Semiconductor Sales contact for further information.
Typical UVLO is set to 3.0 V. Additional thresholds can be manufactured. Please contact your ON Semiconductor Sales contact for further information.
The microcontroller can take into account Flag status and controls thanks to EN pin the pass element state.
The OVP device can be forced to off state thanks to this pin.
When internal junction temperature is exceeded, the pass element is turned off.
Very small package, small thickness.
Low cost version.
