  • Circuit for driving an inductive load, corresponding device, vehicle and method
    Patent number: 11789048
    Abstract: An embodiment circuit comprises high-side and low-side switches arranged between supply and reference nodes, and having an intermediate node. A switching control signal is applied with opposite polarities to the high-side and low-side switches. An inductive load is coupled between the intermediate node and one of the supply and reference nodes. Current sensing circuitry is configured to sample a first value of the load current flowing in one of the high-side and low-side switches before a commutation of the switching control signal, sample a second value of the load current flowing in the other of the high-side and low-side switches after the commutation of the switching control signal, sample a third value of the load current flowing in the other of the high-side and low-side switches after the second sampling, and generate a failure signal as a function of the first, second and third sampled values of the load current.
