Une programmation externe est utilisée pour fixer le point de fonctionnement magnétique alors que l’hystérésis reste fixe. Cette caractéristique avancée permet une optimisation du point de basculement du capteur et peut réduire drastiquement les effets de tolérance de placement lors du processus de production du client final. Les autres paramètres programmables sont la polarité de la sortie ainsi que le temps de descente de la sortie pour réduire la CEM dans les applications automobiles. La technique propriétaire de réduction dynamique de l’offset, associée à une horloge interne haute fréquence, réduit la tension d’offset résiduelle qui est normalement causée par le surmoulage du capteur, les variations en température, et les contraintes thermiques. Le fait d’avoir l’élément hall et l’amplificateur sur la même puce minimise beaucoup de problèmes habituellement associés à des signaux analogiques de faibles niveaux.
\nCe composant intègre un régulateur pour un fonctionnement de 3 V à 24 V, les protections contre les tensions transitoires de l’alimentation, la sortie en court-circuit et contre une tension batterie inverse. Il est proposé dans un boîtier traversant trois broches, garanti sans plomb avec un étamage du lead frames 100% étain mat.<\/p>\n
