US16855

UNISONIC TECHNOLOGIES CO., LTD 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 SOP-8 „ ORDERING INFORMATION Ordering Number Lead Free Halogen Free US16855L-S08-R US16855G-S08-R US16855L-S08-T US16855G-S08-T Note: xx: Output Voltage, refer to Marking Information.
