RT9711GS

IC PWR SWITCH USB 1.5A 8SOP

General Description

The RT9711 is a low voltage, single N-Channel MOSFET high-side power switch, optimized for self-powered and bus- powered Universal Serial Bus USB applications. The RT9711 equipped with a charge pump circuitry to drive the internal MOSFET switch; the switch"s low RDSON, 80mΩ, meets USB voltage drop requirements; and a flag output is available to indicate fault conditions to the local USB controller.
