com Preliminary RT9703 80mΩ, 3A Smart Universal Power Switch with Flag 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 DS(ON) ≈ dd 80m Ω 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 limi...
