Abstract

L'invention présente un dispositif électronique (1) pour un dispositif d'éclairage automobile, comprenant un pilote (2) et un mélangeur (3). Le circuit d'attaque (2) comprend une entrée de puissance et de signal (21) et possède un seuil de tension d'alimentation, de telle sorte que le microcontrôleur est configuré pour se réinitialiser si la valeur de tension dans l'entrée de puissance et de signal (21) est inférieure au seuil de tension d'alimentation. Le mélangeur (3) comprend une sortie (34) connectée à l'entrée d'alimentation et de signal (21) du circuit d'attaque (2), et est configuré pour fournir un signal de sortie qui est lié au plus élevé entre le signal non permanent et les entrées de signal permanentes.Figure pour l'abrégé : figure 1
