RT9711C 1.5A/0.6A High-Side Power Switches

The RT9711A/B/C/D are cost-effective, low voltage, single N-MOSFET high-side power switches, optimized for selfpowered 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 RDS(ON), 80mΩ, meets USB voltage drop requirements. A flag output is a.

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, fault current is limited to typically 2.5A for RT9711A/B in dual ports and 1A for RT9711C/D in single port in accordance with the USB power requirements, lower quiescent current as 25μA making this device ideal for portable battery-operated equipment. The RT9711 series are available in SOT-23-5, TSOT-23-5, SOP-8 and MSOP-8 packages fitting diff.
