Automotive angle sensor offers fast accurate data acquisition and angle measurement

Monolithic Power Systems (MPS) MAQ473 MagAlpha Automotive Angle Sensor is designed to detect the absolute angular position of a permanent magnet, usually a diametrically magnetised cylinder on a rotating shaft. Fast data acquisition and processing gives accurate angle measurement at speeds from 0rpm to 60,000rpm. The device supports a broad variety of magnetic field strengths and spatial configurations. End-of-shaft and off-axis (side-shaft mounting) configurations are both supported.

It provides magnetic field strength detection with programmable thresholds to enable sensing of the magnet position relative to the sensor to create functions, including the sensing of axial movements or diagnostics.

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

The a is AEC-Q100 qualified and is available in a 3mm x 3mm QFN-16 package with wettable flanks.
