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.

Abstract: A circuit includes an input terminal, a first transistor, a second transistor, a comparator, a voltage reference circuit, and a control circuit. The first transistor includes a first terminal coupled to the input terminal. The second transistor includes a first terminal coupled to the input terminal. The comparator includes a first terminal coupled to the input terminal. The voltage reference circuit is coupled to a second terminal of the comparator. The control circuit includes an input, a first output, and a second output. The input is coupled to an output of the comparator. The first output is coupled to a second terminal of the first transistor. The second output is coupled to a second terminal of the second transistor.
