Abstract: A power circuit with a first transistor, including a first terminal connected to a first node, a second terminal connected to an input node, and a control terminal connected to a first control node, and a second transistor, including a first terminal connected to the first node, a second terminal connected to an output node, and a control terminal connected to a second control node. A third transistor includes a first terminal connected to the first control node, a second terminal connected to a second node, and a control terminal, and a fourth transistor includes a first terminal connected to the output node, a second terminal connected to the second control node, and a control terminal connected to a third node. The power circuit also includes a current limiting circuit coupled between the second node and the third node.

Abstract: Aspects of the disclosure provide for a circuit. In at least some examples, the circuit includes a high-side power transistor, a low-side power transistor, a first transistor, a second transistor, and a third transistor. The high-side transistor is adapted to couple between an input node and a switch node. The low-side transistor is coupled between the switch node and ground. The first transistor is adapted to couple between a first node and the switch node. The second transistor is coupled between the first node and an output node. The third transistor is coupled between the first node and ground.
