Abstract: A method is provide for controlling an inductive load device (ILD). The method includes providing a voltage potential across ILD and disabling a flow of current through the ILD resulting from the voltage potential across the ILD when a voltage across a sensing device rises to substantially equal an upper threshold value. The rate at which the voltage across the sensing device rises is a function of resistive and inductive characteristics of the ILD. The method additionally includes enabling the flow of current through the ILD resulting from the voltage potential across the ILD when the voltage across the sensing device decays to substantially equal a lower threshold value. The rate at which the voltage across the sensing device decays is a function of the resistive and inductive characteristics of the ILD.
