ABSTRACT:
A method and a device for switching off an inductive load in a failsafe manner are proposed. According to one aspect of the invention, the method and the device are configured such that a predefined inductive voltage is generated during switch-off. The predefined inductive voltage is monitored by means of a monitoring circuit. In a preferred embodiment, the inductive voltage is set by means of threshold switches and the inductive voltage also is monitored by means of these threshold switches.
