RT9711 1.5A High-Side Power Switches

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 RDS(ON), 80mΩ, meets USB voltage drop requirements; and a flag output is available to indicate .

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. The maximum current is limited to typically 2.5A in dual ports in accordance with the USB power requirements, lower quiescent current as 25μA making this device ideal for portable battery-operated equipment. The RT9711 is available in SOT-23-5 and SOP-8 packages requiring minimum board space and smallest components. Features z z Compliant to .
