Triaxis® Position Sensor

MLX90363
The MLX90363 is the Generation II½ of Triaxis® Position Sensor.

Thanks to an Integrated Magneto-Concentrator (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 - complete revolution) 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 MLX90363 is able to address linear stroke (displacement) position sensor, absolute rotary position sensor with a through-shaft magnet and also 3D "Joystick" applications.

Designed to be paired with an off-the-shelf microcontroller (host), the MLX90363 relies on SPI output communication.

Maximum flexibility for applications development can be accomplished with the MLX90363. The range of position sensing applications are limitless and constrained only by the imagination of the designer. 3D, rotary, linear or even mixed mode implementations can be accomplished through embedded software in the customer’s microcontroller.

All internal raw (Bx, By, Bz) and conditioned signals can be communicated over the SPI channel. Data from the on chip temperature sensor and from the internal chip diagnostics can also be digitally transmitted. Programming (Calibration) happens through the same channel.

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 MLX90363 is offered as an ASIL-B SEooC (Safety Element out of Context - ISO 26262) component.
