US201/US201A

Preliminary

CMOS IC

80mΩ, 500mA/1.1A HIGH-SIDE

POWER SWITCHES WITH FLAG

DESCRIPTION

The UTC US201/A series are 80mΩ, 500mA for US201 (1.1A for

US201A) 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, 1.7V 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 800mA (UTC US201,

single port) and 1.5A (UTC US201A, dual ports).

FEATURES

* 80mꢀ(Typ) N-Channel MOSFET

* Supply Current:

– Switch on : 25μA(Typ)

– Switch off : 1μA (Typ)

* Load Current 500mA for US201 and 1.1A for US201A

* Input Voltage from 2V to 5.5V

* In off-State: Output Voltage can be Higher than Input
