US211A Datasheet, UTC

* 80mΩ(Typ) N-Channel MOSFET * Supply Current:
  – Switch On : 25μA(Typ)
  – Switch Off : 1μA (Typ) * Load Current 500mA for US211 and 1.0A f.

This MOSFET should be driven by a charge pump circuitry inside. Its switch on resistance is as low as 80mΩ which we kno.

The UTC US211/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 resist.
