La régulation du courant de chaque sortie pilotant les LED est réalisée par une simple résistance de référence. La précision du courant dans chaque branche est atteinte sans besoin d’une résistance de ballast. Deux entrées sont disponibles pour la commande on\/off et le signal de contrôle de maître (on\/off\/dim-up\/dim-down). Ce composant permet de piloter deux lignes de LED jusqu’à 200 mA chacune. Les sorties peuvent être mises en parallèle où non utilisées suivant le besoin. Une détection de court-circuit est fournie pour protéger les LED et le circuit lors d’un court-circuit à la masse de l’une des pattes d’une LED. La sortie redémarre le courant régulé automatiquement quand le court-circuit disparaît. Une surveillance de la température permet de réduire le courant de commande quand la température du circuit dépasse une limite thermique ajustable.
\nCe driver de LED est proposé dans un boîtier étroit SOIC 8 pattes avec une semelle dissipatrice pour des performances thermique améliorées. Il fonctionne dans la gamme de température automobile de -40 °C à +125 °C.<\/p>\n
