A device for supplying power to an inductive load includes a switching structure designed to control a current in the load, and elements for detecting anomalies designed to generate information on detection or information on non-detection of an anomaly of the short-circuit type able to occur in the cabling toward the load, in combination with information on validity of the information on non-detection of anomalies. The information on anomaly non-detection is delivered without setting the validity information if the measured current at the end of an appropriate time window is less than a given value of current.
