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.
