A driver circuit for electronically actuating in a predetermined sequence, a plurality of solenoids (54). The driver circuit includes a single boost circuit (22) having an inductor (118) for receiving energy from a power supply and a capacitor (110) for storing a portion of this electrical energy prior to activation of a particular solenoid. The driver circuit further includes circuitry associated with each solenoid (40, 80, 82, 84) for energizing the solenoid by causing the capacitor (110) to discharge therethrough and to regenerate the stored voltage potential prior to the time for energizing another solenoid, The drive circuit further includes a current regular and mode control (70, 150, 170) to control the magnitude of current flowing through each solenoid.
