POWER DISTRIBUTION

SWITCH

DESCRIPTION

The UTC US206 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 US206 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 US206 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.
