DESCRIPTION

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 RDS(ON) which meets the requirements of USB voltage drop is as low as 80mΩ

FEATURES
