A driver supplies an output voltage to an inductive load. The driver includes an input to receive a pulse width modulated control signal having a controllable duty cycle within a predetermined range. A first switch circuit receives a first switch signal to supply a first voltage, a second switch circuit receives a second switch signal to supply a second voltage, and the output voltage is the difference between the first voltage and the second voltage. An inverter and delay circuit receives the control signal to supply the first switch signal and the second switch signal being inverted and delayed with respect to each other. The delay of the delay circuit is selected to obtain an output voltage having a single polarity for each one of the controllable duty cycles within the predetermined range. |
