RT9711BGB

RICHTEK  RT9711BGB  电源负载开关, 高压侧, 低电平有效, 1路输出, 5.5V, 2.5A, SOT-23-5

General Description

The RT9711A/B/C/D are cost-effective, low voltage, single N-MOSFET high-side power switches, optimized for self powered and bus-powered Universal Serial Bus USB applications. The RT9711 series are equipped with a charge pump circuitry to drive the internal MOSFET switch. The switch"s low RDSON, 80mΩ, meets USB voltage drop requirements. A flag output is available to indicate fault conditions to the local USB controller.
