1 / 8 page UNISONIC TECHNOLOGIES CO., LTD US3076-US3376 Preliminary CMOS IC www.unisonic.com.tw 1 of 8 Copyright © 2011 Unisonic Technologies Co., Ltd QW-R502-424.d DUAL USB HIGH-SIDE POWER SWITCH 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. A built-in charge pump is used to drive the N-channel MOSFET that is free of parasitic body diode to eliminate any reversed current flow across the switch when it is powered off. The UTC US3076-US3376 is applied in high-side power protection switch, USB power management, USB host and self-powered bubs, USB bus-powered hubs, hot plug-in power supplies, and battery-charger circuits.
