Summary of 3D MAGNETIC FIELD SENSOR ALLOWS THE SELECTABLE MEASUREMENT OF X, Y, AND Z MAGNETIC FIELDS
Melexis announced the MLX90395 Triaxis Magnetometer Node, an AEC-Q100 automotive-grade monolithic Hall-effect sensor providing contactless 3D sensing with selectable 16-bit digital outputs. Available in medium- and high-field versions and three packages (SOIC-8, TSSOP-16 dual-die for redundancy, and QFN-16 with wettable flanks), it supports I2C and SPI, operates from -40°C to +125°C, and is RoHS compliant. The dual-die option offers redundancy for critical applications like gear lever position sensing, and the Triaxis technology enables smaller, more power-efficient multi-axis magnetic field measurement.
Parts used in the MLX90395 Triaxis Magnetometer Node:
- MLX90395 Triaxis Magnetometer Node (monolithic Hall-effect sensor)
- SOIC-8 package option
- TSSOP-16 package option (dual-die for redundancy)
- QFN-16 package option (with wettable flanks)
- Medium-field version (50 mT)
- High-field version (120 mT)
- I2C digital interface
- SPI digital interface
The Belgium-based global supplier of micro-electronic semiconductor solutions, Melexis has announced the MLX90395 Triaxis Magnetometer Node, an automotive-grade (AEC-Q100) monolithic sensor that uses the Hall effect to provide contactless 3D sensing in three dimensions.

The dual-die version of the MLX90395 provides redundancy for demanding scenarios, such as gear lever position sensing in automotive applications. The functionality of the MLX90395 is defined through the system processor, rather than hardwired into the device itself.
In terms of its applicability to position sensing, it has practically unlimited scope. The MLX90395 offers both I2C and SPI interfaces, making it simple to integrate into an automotive or industrial control environment. Both medium-field (50 mT) and high-field (120 mT) versions are available in three package options: SOIC-8, TSSOP-16 (dual-die for redundancy) and QFN-16 (with wettable flanks).
All package options are qualified to AEC-Q100 covering the extended temperature range for -40°C to +125°C and are RoHS compliant. The selectable digital output provides 16-bit resolution for X, Y and Z magnetic field measurements, enabling the host processor, DSP, microcontroller or digital signal controller to decode the absolute position of any magnet as it passes the sensor. The MLX90395 is smaller and more power-efficient than alternative Hall effect sensors, thanks in large part to Melexis’ Triaxis technology.
