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 R_DS(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 US3X77 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, battery-charger

circuits.


