1. A control circuit comprising:

  • (a) a voltage source;

    (b) a divider circuit having at least one input connected to said voltage source, said divider circuit further including a first transistor and a second transistor;

    (c) a voltage monitor connected to an output of said first transistor;

    (d) an inductive load connected to an output of said second transistor for connecting said inductive load to said voltage source;

    (e) a voltage comparator including a source of reference potential and an input from said voltage monitor;

    (f) a pulse source connected to an output from said voltage comparator; and

    (g) a switching circuit including an input from said pulse source, said switching circuit capable of controlling said divider circuit to selectively disconnect said inductive load from said voltage source.
