DESCRIPTION
5
The UTC US206 is a power distribution switch. It particularly
designed for self-powered and bus-powered Universal Serial Bus
(USB) applications.

The RDS (ON) of the MOSFET switch is as low as 85mΩ. OC is
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.
