CMOS IC

HIGH-SIDE POWER SWITCHES

WITH FLAG



DESCRIPTION

The UTC US201/A/B/C series are 80mΩ high-side power

switches. There’s internal single low voltage N-Channel MOSFET

which makes it an ideal for all USB applications. This MOSFET

should be driven by a charge pump circuitry inside. Its switch on

resistance is as low as 80mꢀ which we know specially meets the

drop voltage for USB applications.

The flag pin can output an open-drain fault flag to next controller.

There’re lots internal special ways for protecting the chip’s

operation.

When in hot-plug events, there’s large current which can create

the upstream voltage droop to match the USB’s voltage droop

requirements and soft-start for isolating the power source.

As soon as the die temperature is higher than 130℃, the internal

shutdown circuit will work.

Only when there’s a normal input voltage in the V_INpin, the

UVLO (under-voltage lockout, 1.3V/2.5V typ.) can make sure the

chip is till in the off state.

Because of the requirement of USB power the fault current

should be ensured less than 0.6A/1.1A (UTC US201/A, single port)

and 1.3A /1.5A (UTC US201B/C, dual ports).


