ABSTRACT:
A clamping circuit for protecting circuits operatively connected between a control circuit, a driving circuit, a power source, and an output circuit includes an inductive flyback circuit to add current to the output circuit through the driving circuit, and a reverse power protection circuit operatively connected between the inductive flyback circuit and the control circuit wherein the reverse power protection circuit opens the inductive flyback circuit and provides an electrical connection between the power source and the output circuit allowing current to flow through the output circuit when the power source is connected to the driving circuit incorrectly.
