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 switch's low RDS(ON) 80m, meets USB voltage drop requirements; and a flag output is available to indicate fault conditions to the local USB controller. Additional features include soft-start to limit inrush current during plug-in, thermal shutdown to prevent catastrophic switch failure from high-current loads, under-voltage lockout (UVLO) to ensure that the device remains off unless there is a valid input voltage present, lower quiescent current as 25A making this device ideal for portable battery operated equipment. The RT9706 is available in SOT-23-5 package requiring minimum board space and smallest components.
