US3577
Overview
The UTC US3X77 is a power distribution switch and particularly designed for self-powered and bus-powered Universal Serial Bus (USB) applications. The UTC US3X77 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.
