General Description
The RT9703 is a low voltage, high performance single
N-Channel MOSFET power switch, designed for power
rail on/off control with low R

and full
protection functions. The RT9703 equipped with a charge
pump circuitry to drive the internal MOSFET switch and a
flag output is available to indicate fault conditions against
large di/dt which may cause the supply to fall out of
regulation. In order to fit different application, an IP pin is
offered for current limit point setting, a resistor from IP to
ground sets the current limit for the switch.
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, a precision
resistor-programmable output current limit up to 3.5A.
Besides, the lower quiescent current as 30
μ
A making this
device ideal for portable battery-operated equipment.
The RT9703 is available in SOP-8 package requiring
minimum board space and smallest components.
