P5.3 - Architecture of an Integrated AMR Current Sensor (IACS) System for a Wide Range of Automotive Applications

W. Schreiber-Prillwitz, A. Nebeling, G. Von Manteuffel & Ch. Nau
A new anisotropic-magneto-resistive-effect (AMR) based current sensor system is presented, with special emphasis on features and design aspects to e considered using this 'system-in-a-package' approach. Besides Hall-sensors, AMR-based sensors are increasingly entering the field of angular and linear position as well as current measurement. The described current sensor is designed for high resolution and fast electronic measurement of DC, AC or pulsed currents. The sensor exhibits no hysteresis as is present in iron core based...
