Triaxis® position sensor IC - MLX90360
Product description
Not recommended for new designs. Replaced by MLX90365. This IC has the same functionality and pin-out as the compared device. Melexis does not recommend using this part in a new design but continues to produce it for existing customers.
The MLX90360 is the second generation of Triaxis® position sensor IC. Thanks to an IMC on its surface, the monolithic device senses, in a contactless fashion, the three spatial components (i.e. Bx, By and Bz) of the applied magnetic flux density. This unique sensing principle applied to a position sensor results into an impressive robustness of the position signal over the mechanical (airgap, off-axis) tolerances.
The rotation of this horizontal component is sensed over a wide range (up to 360º) and processed by the on-chip DSP to ultimately report the absolute angular position of the end-of-shaft magnet.
Alternatively, through measuring individually the horizontal and vertical components, the MLX90360 is able to address linear stroke (displacement) position sensor and also absolute rotary position sensor with a through-shaft magnet. The MLX90360 reports either a ratiometric analog output or a PWM signal.
From the sensing and reporting perspectives, the MLX90360 is an extremely versatile product for any stand-alone remote position sensor application. The output transfer characteristic is fully programmable (e.g. offset, gain, clamping levels, linearity, thermal drift, filtering, range...) to match any specific requirement through end-of-line calibration. The Melexis programming unit PTC-04 communicates and calibrates the device exclusively through the connector terminals (Vdd-Vss-Out).
The MLX90360 targets and is used in a myriad of non-contacting rotary position sensor applications which are frequently seen in automotive and industrial systems. The IC is available in single and dual redundant implementations to cost-effectively address the full range of applications, including safety critical sensing requirements.
The MLX90360 is pin-to-pin compatible with the first generation Triaxis® position sensor ICs:

Back-end calibration of magnetic position sensors
This video explains the concept of the back-end calibration: a feature of our magnetic position sensors that allows you to compensate for non-linearity error in your application. Different methods of calibration and examples are presented. This will help you understand how to use the calibration and why you may need it.
