Melexis MLX90392 Triaxis Micropower Magnetometer

Melexis MLX90392 Triaxis® Micropower Magnetometer is a programmable sensor IC offering a 16-bit output proportional to the magnetic flux density sensed along the XYZ axes, along with temperature output signal. The MLX90392 is based on Melexis proprietary Triaxis technology. By selecting which axes are to be measured, the raw data can be used as input for further post-processing by an external microcontroller, making the device suitable for applications such as joysticks, rotary knobs, linear strokes, and complex 3D position sensing.

The MLX90392 is available in 2 magnetic variants:

  • ±5mT range for low noise applications (MLX90392ELQ-AAA-010-xx)
  • ±50mT range for for position sensor applications (MLX90392ELQ-AAA-011-xx)

The Melexis MLX90392 Triaxis Position Sensor is offered in a compact 2.0mm x 2.5mm UTDFN-8 package, ideal for space-constrained applications.
