Abstract: In an example, a circuit includes a first transistor having a control terminal coupled to a voltage terminal, having a first terminal coupled to a ground terminal, and having a second terminal. The circuit also includes a second transistor having a control terminal coupled to the second terminal of the first transistor, having a first terminal coupled to the ground terminal, and having a second terminal. The circuit includes a diode having a first terminal coupled to the control terminal of the second transistor and having a second terminal coupled to a load terminal. The circuit also includes a third transistor having a control terminal coupled to the second terminal of the second transistor, a first terminal coupled to the voltage terminal, and a second terminal coupled to the load terminal.

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.

Abstract: In an example, a system includes a first transistor and a second transistor, the first transistor and the second transistor configured to provide current to a load. The system also includes a sense transistor coupled to the first transistor, the sense transistor configured to sense a current flowing through the first transistor. The system includes an amplifier coupled to the sense transistor, where the amplifier includes a first input, a second input, and an output. The system also includes pre-bias circuitry coupled to the amplifier, where the pre-bias circuitry is configured to provide a voltage to the first input of the amplifier responsive to the first transistor being off, where the voltage biases the amplifier.
