The BMM350 is a 3-axis magnetic sensor which operates in automatic mode or triggered mode. The magnetic-to-digital conversion technology is based on TMR (tunnel magneto resistance) The BMM350 is designed to meet all requirements for high performance consumer applications such as magnetic compass, virtual, augmented and mixed reality applications and high-end gaming, platform stabilization applications such as image stabilization, or indoor navigation and dead-reckoning, for example in robotics applications.

Evaluation circuitry converts the output of the magnetic transducer sensing structures, developed, produced and tested in BOSCH facilities. The corresponding chip-sets are packed into one single WLCSP 1.28mm x 1.28mm x 0.5mm housing. For optimum system integration the BMM350 is fitted with digital interfaces (I2C, I3C), offering a wide VDDIO voltage range from 1.72V to 3.6V. To provide maximum performance and reliability each device is tested and ready-to use calibrated. 

The BMM350 has an excellent temperature behavior with an outstanding low temperature coefficients of the offset (TCO) and of the sensitivity (TCS). An API is provided for quick integration into the target system.
