Abstract: A device for protecting an electronic equipment item, configured to limit the electric current between an electric power generator and an electronic equipment item consuming electric power. The device includes a control circuit connected to a power circuit, the power circuit including power semiconductors, the power circuit being able to be connected in series between the electric power generator and the electronic equipment item. The control circuit includes event detection modules, a current setpoint variation module, and a control module for controlling the power semiconductors, configured to supply a control signal for limiting the electric current in the power circuit as a function of the current limitation setpoint signal.
