US3176

DESCRIPTION

The UTC US3076-US3376 is an integrated dual channel for USB

high-side power switch. It particularly designed for self-powered and

bus-powered Universal Serial Bus (USB) applications.

The R DS(ON) of the MOSFET switch is as low as 87mΩ. OC which is

open-drain output report over-current or over-temperature event, has

deglitch timeout period typically 9ms.

The UTC US3076-US3376 incorporates some protection circuits,

such as current limiting circuit with foldback function, thermal shutdown

circuit which is designed to prevent catastrophic switch failure due to

increasing power dissipation when continuous heavy loads or short

circuit occurs. 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 US3076-US3376 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,  and

battery-charger circuits.
