US3026A
DUAL-CHANNEL USB POWER
SWITCH AND OVER-CURRENT
PROTECTION
CMOS IC
DESCRIPTION
The UTC US3026A is a standard dual channels power switch with
independent over-current protection fault flag functions, optimized for
bus-powered Universal Serial Bus (USB) and self-powered
applications, including Notebook and desktop PC’s that supply
power to more than one port.
The UTC US3026A also offers thermal shutdown protection that
reduces current consumption in fault modes for each switch and the
entire device. With a 1ms delay on the fault FLAG output prevents
erroneous over current reporting caused by in-rush currents during
hot-plug events.
In addition, the UTC US3026A employs soft-start circuitry that
minimizes in-rush current in applications where highly capacitive
loads are employed.
