Melexis – MLX90393: Micropower Triaxis® Magnetometer

MLX90393: Micropower Triaxis® Magnetometer

The MLX90393 offers programmable duty cycles in the range of 0.1% to 100%. It can be reprogrammed to different modes and with different settings at runtime. The sensor provides a 16-bit output proportional to the magnetic flux density sensed along the XYZ axes using the Melexis proprietary Triaxis technology and also offers a temperature output signal. These digital values are available via I2C and SPI, where the MLX90393 is a slave on the bus. By selecting which axes are to be measured, the raw data can be used as input for further post-processing, such as for joystick applications, rotary knobs, and more complex 3D position sensing applications.
