Melexis Melexis MLX90393 Triaxis® 微功率磁强计

Melexis MLX90393 Triaxis® Micropower Magnetometers are designed for micropower applications, with programmable duty cycles in the range of 0.1% to 100% duty cycle. The MLX90393 series can be reprogrammed to different modes and with different settings at runtime. These sensors offer 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.

The Melexis MLX90393 Triaxis Micropower Magnetometer is offered in compact QFN-16 and UTDFN-8 package, ideal for space-constrained applications.
