Triaxis® position sensor IC - MLX90367

Product description

The MLX90367 is the generation II½ of Triaxis® position sensor IC featuring SAE J2716/SENT protocol. 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 MLX90367 is able to address linear stroke (displacement) position sensor and also absolute rotary position sensor with a through-shaft magnet. From the sensing and reporting perspectives, the MLX90367 is an extremely versatile IC 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 MLX90367 targets and is used in a myriad of non-contacting rotary position sensor applications in automotive systems requiring SAE-J2716/SENT protocol. 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 MLX90367 is offered as an ASIL-B SEooC (Safety Element out of Context - ISO 26262) component. The MLX90365 is pin-to-pin compatible with the generation I½ of Triaxis® position sensor featuring SAE-J2716/SENT (MLX90324).
