MA330 detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. Fast data acquisition and processing provide accurate angle measurements at speeds from 0rpm to 60,000rpm. The digital filtering is adjustable to optimize control loop performance when used in servo applications. The MA330 supports a wide range of magnetic field strengths and spatial configurations. The MA330 features magnetic field strength detection with programmable thresholds to allow sensing of the magnet position relative to the sensor for creation of functions, such as the sensing of axial movements or for diagnostics. On-chip, non-volatile memory provides storage for configuration parameters, including the reference zero angle position, ABZ encoder settings and magnetic field detection thresholds. Applications include brushless DC motor servo drives, motor commutation, motor speed and position control and robotics.
