UNISONIC TECHNOLOGIES CO., LTD US3076-US3376 Preliminary DUAL USB HIGH-SIDE POWER SWITCH CMOS IC  DESCRIPTION The UTC US3076-US3376 is an integrated dual channel for USB high-side power switch. It particularly designed for self-powered and bus-powered Universal Serial Bus (USB) applications. The RDS(ON) of the MOSFET switch is as low as 87mΩ. OC which is open-drain output report over-current or over-temperature event, has deglitch timeout period typically 9ms. The UTC US3076-US3376 incorporates some protection circuits, such as current limiting circuit with foldback function, thermal shutdown circuit which is designed to prevent catastrophic switch failure due to increasing power dissipation when continuous heavy loads or short circuit occurs.
