US3076-US3376
Preliminary
DUAL USB HIGH-SIDE POWER
SWITCH
„ 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.
