Abstract

A circuit configuration for monitoring and/or for regulating supply voltages. The circuit enables at least two supply voltages (U<SUB>12</SUB>) or (U<SUB>22</SUB>) that are produced by means of two feed-ins (Q 1 , Q 2 ) and that are provided for consumer circuits (V 1 , V 2 ) to be monitored and limited simultaneously. To this end, the circuit configuration comprises a corresponding voltage monitoring electronics unit which detects the supply voltages (U<SUB>12</SUB>, U<SUB>22</SUB>) and compares them with associated tolerance values (DeltaU<SUB>12</SUB>, DeltaU<SUB>22</SUB>). The voltage monitoring electronics unit also provides a control signal (y) which signals whether the first supply voltage (U<SUB>12</SUB>) is lower than the associated tolerance value (DeltaU<SUB>12</SUB>). The control signal (y) is used to control a shunt electronics unit through which a shunt current (I<SUB>S</SUB>) passes temporarily. Said shunt current (I<SUB>S</SUB>) is fed by feed-in (Q 1 ) and by feed-in (Q 2 ) and passes through the shunt electronics unit at least when the control signal (y) signals that at least the supply voltage (U<SUB>12</SUB>) is greater than the associated tolerance value (DeltaU<SUB>12</SUB>).
