A recirculating driver control circuit for an electrically operated device has a power supply and a controller coupled to the power supply and the device. The controller generates an on/off signal through a first output. The on/off signal has an ON state and an OFF state. The controller generates a pulse width modulated signal through a second output. The pulse width modulated signal has a first state and a second state. A first switching device is coupled to the first output of the controller and the device and receives the on/off signal. The first switching device conducts when the on/off signal is in the ON state. A second switching device is coupled to the second output of the controller and the electrical device. Energy is supplied to the device when the pulse width modulated signal is in the first state and the on/off signal is in the ON state. The device recirculates energy to power supply when the pulse width modulated signal is in the second state and the on/off signal is in the ON state.
