The FP6861C is a cost-effective, low voltage, single N-Channel MOSFET high-side power switch,
optimized for self-powered and bus-powered Universal Serial Bus (USB) applications.

The FP6861 is equipped with a charge pump circuitry to drive the internal MOSFET switch. The switch’s low RDS(ON) meets USB voltage drop requirement, and a flag output is available to indicate fault conditions to the local USB controller
