Claim 20:
21. A method comprising:
controlling ON/OFF switching of a power switch via a driver circuit;
receiving a first signal on a detection pin associated with the power switch, wherein the first signal corresponds to a first point in time when current is not passing through the power switch and wherein the first signal indicates a first voltage drop over one or more other circuit elements;
receiving a second signal on the detection pin, wherein the second signal, wherein the second signal corresponds to a second point in time when current is passing through the power switch and wherein the second signal indicates a voltage drop over the power switch in combination with a second voltage drop over one or more other circuit elements; and
determining the voltage drop over the power switch based on a difference between the first signal and the second signal.
