Abstract

A method and a device for monitoring at least one output stage for an inductive load using a current regulator and an analysis device are described. A short circuit to a power supply or to ground is detected by comparing at least one current value in a switching phase of the at least one output stage with at least one current value in a free-wheeling phase of the at least one output stage.
