A circuit and a method of controlling a circuit is provided for an electronic control of an electromagnetic drive of an electromagnetic valve. The circuit provides a control signal for the electromagnetic drive which has a high level and a low level. The control signal comprises at least a first time interval having a first duty cycle, an optional second time interval having a second duty cycle, and a third time interval having a third duty cycle, the first, second and third duty cycles being less than one. The first duty cycle is greater than the second duty cycle and the second duty cycle is greater than the third duty cycle. The time length of the time intervals and the size of the duty cycles are configured such that the electromagnetic drive changes from a first operating state to a second operating state in the first time interval, optionally remains in the second operating state in the second time interval, and changes from the second operating state to the first operating state in the third time interval.
