80mΩ, 1.5A High-Side Power Switches with Flag
General Description
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 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 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.
