Triaxis® position sensor IC - MLX90365

Product description

The MLX90365 is the Generation II½ of Triaxis® position sensor IC. Thanks to an IMC on its surface, the monolithic device senses, in a contactless fashion, the 3 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 (Digital Signal Processing) to ultimately report the absolute angular position of the end-of-shaft magnet.

Alternatively, through measuring individually the horizontal and vertical components, the MLX90365 is able to address linear stroke (displacement) position sensor and also absolute rotary position sensor with a through-shaft magnet. The MLX90365 reports either a ratiometric analog output or a Pulse-Width Modulation (PWM) signal. From the sensing and reporting perspectives, the MLX90365 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 MLX90365 targets and is used in a myriad of non-contacting rotary position sensor applications which are frequently seen in automotive and industrial systems. The device is available in single and dual redundant implementations to cost-effectively address the full range of applications, including safety critical sensing requirements.

The MLX90365 is offered as an ASIL-B SEooC (Safety Element out of Context - ISO 26262) component. The MLX90365 is pin-to-pin compatible with the previous generations of Triaxis® position sensor ICs:
