METHOD AND CIRCUIT ARRANGEMENT FOR DETECTING THE STATE OF A LOAD DEVICE WHICH CAN BE CONNECTED TO A SWITCHING CONNECTION |
摘要 |
<p>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.</p> |
