Melexis MLX90393ELW-ABA-011-RE

The MLX90393 brings the highest flexibility in the Triaxis portfolio's smallest packaged assembly. Additionally, the MLX90393 is designed for micropower applications, with programmable duty cycles in the range of 0.1% to 100% allowing for configurable power consumption based on system requirements. The MLX90393 magnetic field sensor can be reprogrammed to different modes and with different settings at run-time to fine-tune the performance and power consumed. The sensor offers a 16-bit output proportional to the magnetic flux density sensed along the X, Y, and Z axes using the Melexis proprietary Triaxis technology and offers a 16-bit temperature output signal. These digital values are available via I²C and SPI, where the MLX90393 is a slave on the bus. Multiple sensors can be connected to the same bus, by A₀ and A₁ hardwired connection (4x) but also through ordering codes with different SW address (4x). By selecting which axes are to be measured, the raw data can be used as input for further postprocessing, such as for joystick applications, rotary knobs, and more complex 3D position sensing applications. Unparalleled performance is achieved with this sensor, which is primarily targeting industrial and consumer applications.
