Abstract: In accordance with an embodiment, a circuit includes: a supply pin and an output pin for connecting a load, and a configuration pin; a semiconductor switch connected between the supply pin and the output pin and configured to establish or to block a current path between the supply pin and the output pin depending on a control signal; and a control circuit configured to generate the control signal for the semiconductor switch taking account of a first parameter, and set the first parameter depending on a component parameter of an external component connected to the configuration pin. The first parameter is set to a first standard value when the component parameter is less than a first threshold value, and the first parameter is set to a second standard value when the component parameter is greater than a second threshold value.

Abstract: An integrated circuit that may be employed as a smart switch is described herein. In accordance with one embodiment the integrated circuit includes a power transistor coupled between a supply pin and an output pin and further includes a control circuit configured to trigger a switch-on and a switch-off of the power transistor in accordance with an input signal. The control circuit is configured to trigger a switch-off of the power transistor when a load current passing through the power transistor is at or above a predetermined current and a supply voltage received at the supply pin is at or below a predetermined threshold voltage.

Abstract: An integrated circuit that may be employed as a smart switch is described herein. The integrated circuit may include a first power transistor coupled between a supply pin and a first output pin and a second power transistor coupled between the supply pin and a second output pin. The first and the second power transistors each having an intrinsic body diode which allows reverse conduction. The integrated circuit further includes a control circuit that is configured to trigger a switch-on and switch-off of the first and the second power transistors based on a first input signal and a second input signal, respectively. Furthermore, the integrated circuit includes a protection circuit configured to detect, for the first and the second power transistors, a transition from a reverse conducting state into a forward conducting state, and vice versa, and to generate an error signal in response to certain detections.
