Abstract: A circuit includes a first transistor, a second transistor, and a sense transistor. The first current terminals of the first and second transistors are coupled together at a power supply node. The control terminals of the second and third transistors are coupled together. The second current terminals of the first, second, and third transistors are coupled together. The sense resistor is coupled between the first current terminals of the first and second transistors and the first current terminal of the third transistor. The first and second transistors are configured such that during a first mode of operation, current to a load flows through the first and second transistors, and during a second mode of operation, current to a load is discontinued through the first transistor yet flows through the second transistor.
