Monolithic Power Systems (MPS) MAQ473 MagAlpha™ Automotive Angle Sensor

Monolithic Power Systems (MPS) MAQ473 MagAlpha™ Automotive Angle Sensor is designed to detect 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 measurement at speeds from 0rpm to 60,000rpm. The MAQ473 supports a wide range of magnetic field strengths and spatial configurations. Both end-of-shaft and off-axis (side-shaft mounting) configurations are supported.

The MAQ473 features magnetic field strength detection with programmable thresholds to allow sensing of the magnet position relative to the sensor for the creation of functions such as the sensing of axial movements or diagnostics.

The on-chip non-volatile memory provides storage for configuration parameters, including the reference zero angle position, ABZ encoder settings, and magnetic field detection thresholds.

The Monolithic Power Systems (MPS) MAQ473 MagAlpha Automotive Angle Sensor is AEC-Q100 qualified and is available in a 3.0mm x 3.0mm QFN-16 package with wettable flanks.
