ABSTRACT:
A circuit for controlling a plurality of inductive loads, includes a plurality of low voltage transistors controlled by a flip-flop so that only one of the low voltage transistors is on at any given time. These low voltage transistors connected one end of respective ones of the loads to one rail of a supply. Diodes connect the other ends of the loads to a common point which is connected to the other rail of the supply by a single high-voltage transistor. Further diodes connect said one end of the respective loads to said other rail to protect the low voltage transistors from high voltages caused by the interruption of current in the loads.
