The RT9711 is a low voltage, single N-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 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. The maximum
current is limited to typically 2.5A in dual ports in
accordance with the USB power requirements, lower
quiescent current as 25uA 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 componen
