Abstract: According to the invention, a circuit arrangement for a starter of a motor vehicle internal combustion engine is proposed, with which the starting relay (4) remains activated during a time-limited voltage dip (undervoltage of the battery). Between a computer (19) and an end stage (3) for triggering the starting relay (4), a memory circuit (2) is connected to a locking circuit (1), which in the event of undervoltage of the battery (20) maintains the status at a control input STEN during the voltage dip. A computer (19) which has entered a reset mode during the voltage dip is reactivated after the termination of the voltage dip and controls the locking circuit (1) in such a way that the starting relay (4) now continues to be triggered via the control input STEN. To obtain a defined outset state of the flip-flop (14, 15) upon reconnection of the battery, an RC member is disposed in the memory circuit.
