Melexis’ MLX90393 series of programmable Triaxis magnetic sensors is designed for micropower applications with programmable duty cycles in the range of 0.1% to 100%. Current supply is a low 4 mA and provides 100 µA output. 

This sensor can be reprogrammed to different modes and with different settings at run-time. The sensor offers a 16-bit output proportional to the magnetic flux density sensed along the XYZ axes using the Melexis’ proprietary Triaxis technology. These digital values are available via I²C and SPI, where the MLX90393 is a slave on the bus. These sensors come in small 3 mm x 3 mm 16-pin QFN package. The MLX90393 is ideal for non-contact HMI applications such as rotary knobs, dials, and joysticks.
