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 ( ) remains activated during a time-limited voltage dip (undervoltage of the battery). Between a computer ( ) and an end stage ( ) for triggering the starting relay ( ), a memory circuit ( ) is connected to a locking circuit ( ), which in the event of undervoltage of the battery ( ) maintains the status at a control input STEN during the voltage dip. A computer ( ) which has entered a reset mode during the voltage dip is reactivated after the termination of the voltage dip and controls the locking circuit ( ) in such a way that the starting relay ( ) now continues to be triggered via the control input STEN. To obtain a defined outset state of the flip-flop ( ) upon reconnection of the battery, an RC member is disposed in the memory circuit.
