Abstract
A circuit configuration for monitoring and/or for regulating supply voltages. The circuit enables at least two supply voltages (U) or (U) that are produced by means of two feed-ins (Q, Q) and that are provided for consumer circuits (V, V) 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, U) and compares them with associated tolerance values (ΔU, ΔU). The voltage monitoring electronics unit also provides a control signal (y) which signals whether the first supply voltage (U) is lower than the associated tolerance value (ΔU). The control signal (y) is used to control a shunt electronics unit through which a shunt current (I) passes temporarily. Said shunt current (I) is fed by feed-in (Q) and by feed-in (Q) and passes through the shunt electronics unit at least when the control signal (y) signals that at least the supply voltage (U) is greater than the associated tolerance value (ΔU).
