Les sorties de ce composant peuvent être connectées en parallèle ou laissées inutilisées. Le courant régulé dans les LEDs est fixé par une résistance externe. Le courant est égalisé dans chaque sortie sans l’ajout de résistance de ballast. Piloter les LEDs à courant constant assure un fonctionnement sûr avec un maximum de lumière délivrée.
\nCe circuit intègre des protections contre une gamme de défauts habituels tels que court-circuit à la masse de la branche de LED, simple ou multiple LED en court-circuit, branche de LED en circuit ouvert, broche du composant en court-circuit ou en circuit ouvert, protection contre les sur températures. Si une branche est en circuit ouvert ou en court-circuit, cette branche est désactivée alors que les autres branches continuent à fonctionner. Une mesure de la température est intégrée pour réduire le courant délivré si la température dépasse un seuil thermique. Si besoin cette réduction peut être ajustée ou désactivée.
\nCe pilote de LED est proposé dans un boitier SOICN 8 broches (suffix LJ) avec une semelle pour améliorer la dissipation thermique et fonctionne dans la plage de température de -40 °C à +125 °C<\/p>\n
