MPS MA782: The World's Smallest Absolute IC Encoder™
An SoC in a ultra-small 2mm x 2mm x 0.9mm package
Using the proprietary SpinAxis™ Hall sensor technology, this encoder provides true absolute position data and can be used on axis, side axis and side axis orthogonal applications. Some potential applications include products requiring low average power consumption, such as battery-powered devices, IoT, HMI, and space-constrained applications such as extremely small motors or mechatronic systems.
The MA782 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 llow the 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, the power cycling parameters, the filter window affecting the output resolution and magnetic field detection thresholds.
