POWER DISTRIBUTION SWITCH
DESCRIPTION
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.
Besides, 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 RDS(ON) of the...
