    Abstract: A method of compensating electromagnetic emissions of a device for use in a communication bus, the method including: transmitting a test signal over the communication bus; receiving, at the device, the test signal after propagation over the communication bus; performing frequency analysis processing of the test signal received to detect a set of harmonic components of the test signal received having an amplitude exceeding a certain threshold; storing respective values of frequency of harmonic components in the set of harmonic components having an amplitude exceeding the certain threshold; and generating and transmitting over the communication bus a set of compensation signals, each compensation signal in the set of compensation signals being a sinusoidal signal having a respective frequency equal to one of the frequencies stored, and being in anti-phase with respect to the harmonic component of the test signal received having the respective frequency.

    Abstract: A driver for an electric load includes a power device having a control terminal and an output terminal for an output current, and a control module. The control module is configured to drive the power device in an auto-recovery mode by switching between activation and deactivation in the occurrence of an overcurrent condition, wherein the output current reaches a threshold current. The control module is also configured to evaluate a first time interval between a time wherein the overcurrent condition occurs, and a first time, and generate a limit signal when the time interval is equal to a time threshold. The power device is driven in a switching-off condition at least as a function of the limit signal.
