US16855
Preliminary
DUAL HIGH-SIDE SWITCH FOR
USB APPLICATION
CMOS IC
DESCRIPTION
The UTC US16855 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 US16855 is equipped with over-temperature
and over-current detectors and each flag output is available to
indicate fault conditions independently to the USB controller. The
UTC US16855 is available in active-high versions in 8-pin SOP
package.
FEATURES
* 4V ~ 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
