Title
(EN) MAGNETORESISTOR INTEGRATED SENSOR FOR MEASURING VOLTAGE OR CURRENT, AND DIAGNOSTIC SYSTEM
(FR) CAPTEUR INTÈGRE DE MESURE DE TENSION OU DE COURANT A BASE DE MAGNÉTORÉSISTANCES
Abstract
(EN)
The invention relates to an integrated sensor, including terminals (1, 2) for connection to an electric generator, said terminals being connected to a metal measuring line (4, 5) in which a current proportional to the voltage or current of the generator to be measured flows, and magnetoresistors (31, 32, 33, 34). The metal measuring line includes elongate and parallel sections (4, 5) in which the current flows in opposite directions, said sections being connected to a portion (3) for closing the metal measuring line (3, 4, 5), which is arranged on a galvanic isolation layer (8) that is in turn arranged on an integrated circuit portion including the magnetoresistors (31, 32, 33, 34), each of which have a sensitive portion that is vertically adjacent to one of the elongate sections (4, 5). The sensor can be integrated into a diagnostic system.

Le capteur intégré comprend des bornes (1, 2) de connexion à un générateur électrique, reliées à une ligne de mesure (4, 5) métallique dans laquelle circule un courant proportionnel à la tension ou au courant du générateur qui est à mesurer, et des magnétorésistances (31, 32, 33, 34). La ligne de mesure métallique comprend des tronçons (4, 5) allongés et parallèles dans lesquels le courant circule en sens opposés, reliés à une portion (3) destinée à fermer la ligne de mesure métallique (3, 4, 5) disposée sur une couche d'isolation galvanique (8), elle-même disposée sur une portion de circuit intégré de détection comprenant les magnétorésistances (31, 32, 33, 34) qui présentent elles-mêmes chacune une partie sensible qui est superposée à l'un des tronçons allongés (4, 5). Le capteur peut être intégré dans un système de diagnostic.
