RT9706
80mΩ, 500mA High-Side Power Switch with Flag
General Description
The RT9706 is a cost-effective, low voltage, single
N-Channel MOSFET high-side power switch, optimized
for self-powered and bus-powered Universal Serial Bus
(USB) applications. The RT9706 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, lower
quiescent current as 25μA making this device ideal for
portable battery operated equipment.
The RT9706 is available in SOT-23-5 package requiring
minimum board space and smallest components.
