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 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, 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 different aspect of
broad applications.
