A procedure and device for overload and shortcircuit protection of output drivers, uses a circuit that functions at several control voltage levels and in which at least one output driver is controlled in a normal situation by a reference value set independently of external control, whereas in a short-circuit or overload situation the driver receives a control voltage for short instants only, and in which the reference value begins to fall rapidly when the load current of the output driver exceeds a set limit.
