The present invention relates to a circuit arrangement for driving an electronic component with the output signal (V6) from a microprocessor (MP), comprising: the electronic component with a control input; a microprocessor (MP), which provides an output signal (V6) at an output (A1); wherein it furthermore comprises: a first bipolar transistor (Q5) in common-base connection, whose emitter is coupled to the output (A1) of the microprocessor (MP); a second bipolar transistor (Q7) in common-emitter connection, whose base is coupled to the collector of the first bipolar transistor (Q5), wherein the collector of the second bipolar transistor (Q7) is coupled to the control input of the electronic component. Moreover, it relates to a corresponding method for driving an electronic component with the output signal (V6) from a microprocessor (MP).

La présente invention concerne une circuiterie servant à commander un composant électronique par le biais du signal de sortie (V6) d'un microprocesseur (MP). La circuiterie selon l'invention comprend le composant électronique muni d'une entrée de commande, un microprocesseur (MP) qui fournit un signal de sortie (V6) au niveau d'une sortie (A1), ainsi qu'un premier transistor bipolaire (Q5) à montage en base commune dont l'émetteur est relié à la sortie (A1) du microprocesseur (MP) et un deuxième transistor bipolaire (Q7) à montage en émetteur commun dont la base est reliée au collecteur du premier transistor bipolaire (Q5), le collecteur du deuxième transistor bipolaire (Q7) étant relié à l'entrée de commande du composant électronique. L'invention concerne en outre un procédé correspondant servant à commander un composant électronique par le biais du signal de sortie (V6) d'un microprocesseur (MP).
