Abstract: A self-protected, low emission electronic device for driving a warning horn includes a coil powered from a battery through a control push-button adapted for operation by a user and included in an electric connection between a terminal of the coil and the battery. The device includes a protective circuit portion connected between the battery and the warning horn. The protective circuit portion includes a bridge structure of power components. At least a pair of the power components are MOS power transistors of which one is driven by a charge pump.
