Product Summary

The RT9711BGB 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 RT9711BGB equipped with a charge pump circuitry to drive the internal MOSFET switch; the switch’s low RDS(ON), 80mΩ, meets USB voltage drop requirements; and a flag output is available to indicate fault conditions to the local USB controller. The applications of the RT9711BGB include USB Bus/Self Powered Hubs, USB Peripherals, ACPI Power Distribution, PC Card Hot Swap, Notebook, Motherboard PCs, Battery-Powered Equipment, Hot-Plug Power Supplies, and Battery-Charger Circuits.
