ABSTRACT:
A driver circuit for limiting the magnitude of current flowing through a solenoid wherein the level of the current flowing through the solenoid is sensed and fed back to a driving switch. A level of current above a set level cuts off the drive voltage allowing the current in the solenoid to decay. A timing means fixes the time that the driving switch is off. During off times a conserving voltage is applied to the solenoid to prevent the rapid decay of the solenoid current.
