Abstract: A protection circuit for protecting a switch from a fault includes a first sensing circuit and a second sensing circuit. The first sensing circuit senses a low-side load current through a switch that includes a first terminal, a second terminal and a control terminal. The first terminal is connected to a low-side of the load and the second terminal is connected to ground. The switch provides a conductive path between the first and second terminals responsive to a control signal provided on the control terminal. The first sensing circuit acts to reduce a magnitude of the control signal to limit the low-side load current, carried by the switch, when the low-side load current exceeds a first predetermined value. The second sensing circuit senses a voltage at the low-side of the load and interrupts the low-side load current, when the voltage at the low-side of the load exceeds a second predetermined value.
