Triaxis® micropower magnetometer (magnetic field sensor IC) - MLX90393

Product description

The MLX90393 is the newest addition to the Melexis position sensing portfolio, bringing the highest flexibility in the portfolio's smallest assembly. Complementing this, the magnetic field sensor IC is designed for micropower applications, with programmable duty cycles in the range of 0.1% to 100%.

The MLX90393 magnetic field sensor IC can be reprogrammed to different modes and with different settings at run-time. The sensor IC offers 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. Unparallelled performance is achieved with this sensor, which is primarily targeting industrial and consumer applications.
