摘要： The proposal is for a device for igniting gas discharge lamps (10, 11) by means of a high-voltage pulse in which one high-voltage generator (16) is allocated to a plurality of lamps (10, 11). The high-voltage generator (16) is connected to the gas discharge lamps (10, 11) to be ignited via high-voltage switching components (14, 15). The high-voltage switching components (14, 15) preferably take the form of radiation-triggered four-layer diodes.

摘要： The invention concerns a circuit for the switching of loads on the basis of an activated signal (INPUT - 5) with at least two connected series. Said connected series result from a logic circuit (3, 4) of controllable MOSFET-output stages (1, 2), by which the electricity supply to the series-connected MOSFET-output stage (2) passes over the first MOSFET-output stage (1). The invention also relates to the mutual monitoring of both MOSFET-output stages (1, 2) to disconnect short circuits by means of a provided connecting line (7) between the logic circuits (3, 4). An input voltage (EN) to the logic circuit (4) of the series-connected MOSFET-output stage (2) travels on said connecting line, thereby providing the average monitoring of electricity supply (LOAD1) in relation to the series-connected MOSFET-output stage (2). These means are activated through the activated signal (INPUT - 5) and prevent the turning on of the first MOSFET-output stage (1) if the electricity supply (LOAD1) is below a predetermined value (short circuit of the series-connected MOSFET-output stage (2)). Means are provided for the adjustment of the input voltage (EN) if the first MOSFET-output stage (1) is turned on by the activating signal (INPUT - 5). Also provided are means for comparing the input voltage (EN) and the electricity supply (LOAD1), whereby they prevent the activation of the second MOSFET-output stage (2) if the supply of electricity (LOAD1) exceeds a certain potential and the input voltage (EN) is below a certain potential (short-circuit of the first MOSFET-output stage (1)).

摘要： The invention relates to a device for starting an internal combustion engine, especially of a motor vehicle, with a starter motor which can be connected via a starter relay to a voltage source and engaged with the engine to start it, and an electronic device for triggering the starter relay. The electronic device (30) takes the form of an electronic relay (32) fitted on or in the starting device (10) which can be triggered via a logic signal input (48) of an electronic engine control device (50) in the motor vehicle.

摘要： The invention relates to a monolithic controller (1) for the generator unit of a motor vehicle which is firmly connected to a heat sink. Preferably, the heat sink is a heat conductive ceramic substrate (4) which is also provided with electrically conductive connections (v1-v5), preferably copper structures. The monolithic controller is firmly connected to the substrate in an unpacked form.

摘要： In order to prevent critical states of the operating condition of a MOS transistor output stage (1) the invention proposes using a circuit for de-activating said MOS transistor output stage (1), in particular a high power transistor, in the event of the occurrence of abnormal potentials on at least one monitored line (4), means being provided for controlling the MOS transistor output stage. The invention is characterised in that means (3) are also provided for monitoring the line (4). The MOS transistor output stage (1) can also be de-activated by means (3) for monitoring the line (4), independently of the means (2) for controlling the MOS transistor output stage (1) (de-activating path II).
