DUAL-CHANNEL POWER

DISTRIBUTION CONTROL

SWITCH FOR USB

DESCRIPTION

The UTC US2075A is a dual channel power switch with

independent enable and flag functions, optimized for bus-powered

Universal Serial Bus (USB) and self-powered applications.

This product satisfies USB voltage drop requirement with soft

start, which eliminates the momentary voltage drop on the upstream

port that may occur.

In addition, the UTC US2075A is equipped with over-temperature

and over-current detectors, each flag output is available to indicate

fault conditions independently to the USB controller. The UTC

US2075A

is available in active-low versions in 8-pin SOP package.

FEATURES

* Under-voltage lockout circuit

* Thermal shutdown circuit

* Soft-start circuit

* Flag indicates fault conditions
