Melexis MLX90393 Triaxis® Magnetic Node offers a 16-bit output proportional to the magnetic flux density sensed along the XYZ axis and a temperature output signal. These digital values are available via I2C and SPI, where the MLX90393 is a slave on the bus. The MLX90393 series can be reprogrammed to different modes along with different settings at run-time. Duty cycles can be achieved in the range of 0.1% to 100% which makes the sensor ideal for micropower applications. The MLX90393 series rely on the Melexis proprietary Triaxis® technology. By selecting which axis are to be measured, the raw data can be used as input for further post-processing, such as joystick applications, rotary knobs, linear strokes and complex 3D position sensing applications.
