| 摘要 |
The present invention relates to a circuit arrangement and a method for load diagnosis of a switch having a first and a second load connecting terminal. A first and a second current source arrangement are provided, which can in each case be connected to one of the load connecting terminals of the switch and which supply, depending on potential conditions at the said load connecting terminals, currents in a first and second current direction or oppositely to the said first and second current direction to the load connecting terminals. Furthermore, an evaluation circuit is provided, which evaluates the currents flowing to the first and second load connecting terminals and provides a load state signal depending on the said currents.
