FP6861C
Single-Channel Power Distribution Switch
Description
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 FP6861C 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.
Additional features include soft-start to limit inrush current during plug-in, thermal shutdown to prevent catastrophic switch failure from high-current loads, and under-voltage lockout (UVLO) to ensure that the device remains off unless there is a valid input voltage present.
