HIGH-SIDE POWER SWITCHES

WITH FLAG



DESCRIPTION

SOT-25

The UTC US203 are low voltage cost-effective high-side power

switches with flag function. These devices are particularly suitable for

self-powered and bus-powered USB applications. The build-in

N-MOSFET’s R_DS(ON)which meets the requirements of USB voltage drop

is as low as 80mΩ.

The UTC US203 contains a charge pump circuitry to drive the internal

MOSFET switch and also incorporate such protection circuits: soft-start

circuit protect these devices from being damaged by limiting inrush

current during plug-in; thermal shutdown circuit is used to prevent

catastrophic switch failure from high-current loads. UVLO is used to

ensure that the device remains off unless there is a valid input voltage

present.

SOP-8

A flag output is designed to indicate fault conditions to the local USB

controller. lower quiescent current as 25μA making this device ideal for

portable battery-operated equipment.

The UTC US203 are applied in USB Bus/Self powered hubs, USB

peripherals, NB, PCs, PC card hot swap, battery-powered equipment,

hot-plug power supplies, battery-charger circuits, ACPI power

distribution.
