摘要： A method for detecting the state of a load device which can be connected to a switching connection, wherein the switching connection can be coupled to, and decoupled from, a predefined switching potential. A voltage drop across the switching connection is used as a basis for detecting whether the load device is connected to the switching connection, the load device is not connected to the switching connection or there is a short circuit between the switching connection and a first or a second switching potential. An additional current source is connected to the switching connection at the same time as the switching connection is decoupled from the predefined switching potential.

摘要： An integrated circuit has a control circuit (2) for a power field-effect transistor (3), wherein the integrated circuit has a first input (202) for receiving a control signal (CE) and an output to switch the field-effect transistor (3) on or off. The control circuit further has a driver circuit for providing a voltage level at the output in response of the control signal. A second input is provided for receiving a configuration signal, the configuration signal for configuring the voltage level being provided by the driver circuit in response to the control signal.
