CMOS IC
„ DESCRIPTION
The UTC US2026A 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
SOP-8
power to more than one port.
The UTC US2026A 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
hot-plug events.

In addition, the UTC US2026A employs soft-start circuitry that
minimizes in-rush current in applications where highly capacitive
loads are employed.
