Abstract
A discharge circuit for demagnetizing an inductive load includes a first switch comprising a control terminal and first and second terminals. The first terminal is connected to a voltage supply. A second switch includes a control terminal and first and second terminals. The second terminal of the first switch and the second terminal of the second switch are connected to the inductive load. A third switch includes a control terminal and first and second terminals. The first terminal of the third switch is connected to the first terminal of the second switch. A first Zener diode includes an anode connected to the control terminal of the second switch and a cathode connected to the voltage supply. A first temperature sensing circuit generates a first sensed temperature signal based on a temperature of at least one component of the circuit. A first comparing circuit receives a first reference temperature signal and the first sensed temperature signal and that generates a first output.
