Summary of MELEXIS MLX90392 TRIAXIS MICROPOWER MAGNETOMETER
Melexis MLX90392 is a programmable Triaxis magnetometer IC providing 16-bit XYZ magnetic and temperature outputs. It supports selectable axes, two magnetic ranges (±5 mT low-noise and ±50 mT position sensing), micropower operation, and I2C communication. Packaged in a compact 2.0 × 2.5 × 0.4 mm UTDFN-8, it suits joysticks, rotary knobs, linear strokes, and 3D position sensing with selectable measurement modes and up to 1.4 kHz data rate.
Parts used in the Melexis MLX90392 Triaxis Position Sensor:
- Melexis MLX90392 Triaxis Micropower Magnetometer IC (UTDFN-8 package)
- ±5 mT magnetic variant MLX90392ELQ-AAA-010-xx
- ±50 mT magnetic variant MLX90392ELQ-AAA-011-xx

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.
