<p align="justify">The RT9703 is a low voltage, high performance single N-MOSFET power switch, designed for power rail on/off control with low R<sub>DS(ON)</sub> ≈ 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.<br />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.<br />The RT9703 is available in SOP-8 package requiring minimum board space and smallest components.</p>
