Melexis MLX90393SLW-ABA-011-RE

霍尔效应X，Y，ZI²C，SPI2.2V ~ 3.6V

Overview

Melexis MLX90393 Triaxis� Micropower Magnetometer duty cycles in the range of 0.1% to 100% duty cycle which make it ideal for micropower applications. The MLX90393 can be reprogrammed to different modes and with different settings at run-time. The MLX90393 sensor using the Melexis proprietary Triaxis technology to offer a 16-bit output proportional to the magnetic flux density sensed along the XYZ axes and 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.
