A method for supplying power to an inductive load () using an H-bridge () power supply structure, comprising a first block Bof steps for detecting an anomaly using a 'DIAG ON' diagnostic method, a second block Bof steps for detecting an anomaly using a “DIAG OFF” diagnostic method, and finally a third block Bof steps for discriminating the detected anomaly and for confirming a short circuit at the inductive load () anomaly.

Method for supplying power to an inductive load

A device for supplying power to an inductive load, including an H-bridge switching structure, the switching structure being designed to drive a current in the inductive load through a first control output and a second control output, an anomaly detector designed to generate an item of anomaly detection information about the detection of an anomaly at the switching structure, the anomaly detector including a first voltage generator, a second voltage generator, a first current measuring device, a second current measuring device designed to measure a current at the output of the second voltage generator, a third current measuring device, a fourth current measuring device, a fifth current measuring device and a sixth current measuring device, the current measuring devices being designed to respectively measure the currents of the switches.
