DUAL-CHANNEL POWER

DISTRIBUTION CONTROL

SWITCH FOR USB

DESCRIPTION

The UTC US2075C 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 US2075C 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

US2075C

is available in active-high versions.

FEATURES

* 100 μA MAX operating current

* 5μA MAX standby current

* 3.5V ~ 5.5V operating range

* Two P-channel power MOSFET control switch

* Over-current protection

* Under-voltage lockout circuit

* Thermal shutdown circuit

* Soft-start circuit

* Flag indicates fault conditions
