The circuit arrangement has a comparator circuit (CP1,CP2), with which a potential (V+,V-) derived from the voltage to be monitored is compared with a reference potential (Vref), for determining a wrong voltage, where potentials are tapped on a voltage divider (102,104). The voltage driver has a series connection of resistances (R1, R2,R4,R5), where resistance is changed within the voltage divider such that a wrong voltage is simulated. An independent claim is included for a method for checking a switching arrangement with a comparator circuit. |
