US3075-US3375
POWER DISTRIBUTION SWITCH
CMOS IC
DESCRIPTION
The UTC US3075-US3375 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 100m. OC is
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.
