Abstract

a. Circuit intégré à effet Hall comportant un servi-conducteur Hall mis en oeuvre par le flux magnétique pour donner un signal de sortie Hall, et qui est traversé par un courant Hall sensible aux variations de température, un circuit de détection ayant une tension de seuil et un courant de fonctionnement, en étant couplé au dispositif à effet Hall pour créer la tension de sortie lorsque le signal de sortie atteint la tension de seuil. b. Circuit caractérisé par un circuit relié au dispositif à effet Hall, et au détecteur pour maintenir le courant de fonctionnement à une valeur ayant une relation prédéterminée au courant Hall pendant les variations de température, pour que le signal de sortie à effet Hall suive la tension de seuil et crée un signal de sortie de détection indépendant des variations de température.
