RT9706集成电路（IC）的配电开关负载驱动器规格书PDF中文资料

General Description

The RT9706 is a cost-effective, low voltage, single N-Channel MOSFET high-side power switch, optimized for self-powered and bus-powered Universal Serial Bus (USB) applications. The RT9706 equipped with a charge pump circuitry to drive the internal MOSFET switch; the switchs low RDS(ON) 80mΩ, meets USB voltage drop requirements; and a flag output is available to indicate fault conditions to the local USB controller.
