The RT9703 is a low voltage, high performance single
N-MOSFET power switch, designed for power rail on/off
control with low RDS(ON) ≈ 80mΩ 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 30μA making this
device ideal for portable battery-operated equipment.
The RT9703 is available in SOP-8 package requiring
minimum board space and smallest components.
