Abstract
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.
