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.
