Magnetometer keeps accuracy while protecting against magnetic fields

This is an ultra-small, high-performance, low-current, 16-bit 3-axis magnetometer, ideally suited for a wide range of consumer applications such as virtual, augmented, and mixed reality applications, head orientation, indoor navigation, magnetic compass, high-end gaming and robotics. 

The magnetometer is based on Bosch's proprietary tunnel magnetoresistance (TMR) technology with field shock recovery features that provide protection against external magnetic fields while ensuring high accuracy.

For augmented reality or virtual reality (AR/VR), ultra-precise digital pathfinding improves tracking of head movements and 3D audio, reducing pixel latency and motion sickness for VR users.

New data-ready interrupt signals and data-ready status register read-out provide the BMM350 instant data updates and status polling of positioning and speed detection for indoor navigation and AR/VR applications.

The magnetometer allows measurements of the magnetic field in three perpendicular axes, with a magnetic field range of typical ± 2000 µT (x, y, z-axis) and a low current consumption of ± 200 µA @ 100 Hz in low power preset.

Combined with a low noise ratio of ± 190 n T_rms for x, y-axis, and ± 450 n T_rms in z-axis, the BMM350 is ideally suited for a multitude of target orientation applications.

The BMM350 sensor module is housed in a compact 9-pin wafer-level chip scale package (WLCSP) with a footprint of only 1.28 mm × 1.28 mm and a sensor height of 0.5 mm. The small dimensions and low power consumption of the sensor make it ideal for use in portable and battery-driven applications.
