UNISONIC TECHNOLOGIES CO., LTD US3075-US3375 POWER DISTRIBUTION SWITCH CMOS IC  DESCRIPTION The UTC US3075-US3375 is a power distribution 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 100mΩ. OC is open-drain output report over-current or over-temperature event which has deglitch typical 9ms timeout period typically 9ms. The UTC US3075-US3375 incorporates protection circuits including current limiting circuit with foldback function, thermal shutdown circuit designed to prevent catastrophic switch failure due to increasing power dissipation when continuous heavy loads or short circuit occurs.
