1. A current limited power device, comprising:
a switch;
an output coupled to the switch;
a sensor coupled to sense a voltage across a parasitic diode within the switch; and
an output current limiter circuit coupled to reduce an output current (Iout) from the output of the power device if the voltage across the parasitic diode exceeds a threshold level.
