Overview
UNISONIC TECHNOLOGIES CO.
, LTD US211/A/B/C Preliminary CMOS IC HIGH-SIDE POWER SWITCHES WITH FLAG  DESCRIPTION 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 resistance is as low as 80mΩ 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...
