POWER DISTRIBUTION SWITCH

DESCRIPTION

The UTC US3075-US3375 is a power distribution switch. It

particularly designed for self-powered and bus-powered Universal

Serial Bus (USB) applications.

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. 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 UTC US3075-US3375 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.
