MA782 is a low power angle sensor with SPI output

MPS MA782 is a 12-Bit, digital low power angle sensor with SPI output – the world’s smallest absolute ICEncoder™.

The MA782 is the world’s smallest absolute ICEncoder™ which detects the absolute angular position of a permanent magnet (typically a diametrically magnetized cylinder on a rotating shaft). With its power cycling ability, the sensor is suitable for applications requiring low average power. The timing can be controlled by an on-chip clock or by an external controller. Flags are available for detecting a definable amount of angle change.

The MA782 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 MA782 features magnetic field strength detection with programmable thresholds to allow the sensing of the magnet position relative to the sensor for the 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, the power cycling parameters, the filter window affecting the output resolution and magnetic field detection thresholds.
