FP6861C PDF – Power Distribution Switch

A power distribution switch, also known as a power switch or load switch, is an electronic component used to control the distribution of power within an electrical or electronic system. It is commonly employed to switch power supply lines on or off to various loads or subsystems.

This post explains for the Distribution Switch.

The Part Number is FP6861C.

The function of this semiconductor is Single-Channel Power Distribution Switch.

The package is MSOP-8, SOP-8 and SOT-23-5 Type

Manufacturer: Fiti ( fitipower integrated technology )

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. […]
