Preliminary
DUAL USB HIGH-SIDE POWER
SWITCH
CMOS IC
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 RDS(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.
