■ DESCRIPTION

The UTC US204 series are 100mΩ high-side power switches. There are internal duel low voltage N-Channel MOSFETS which whish is ideal all USB applications. These MOSFETS is driven by a charge pump circuitry inside, these switches on resistance are as low as 100mΩ which and meet the drop voltage for USB applications.

The flag pins output an open-drain fault flag to next controller. There’re lots internal special ways for protecting the chip’s operation. There are also built-in protection circnits to ensure the chips function normally.
