The BMC150 combines a 12-bit 3-Axis accelerometer and a wide-range 3-Axis geomagnetic sensor in a 2.2×2.2mm LGA package (the smallest footprint at its introduction). All the functionalities are developed and manufactured by Bosch.

Compared to its predecessor BMC050, the BMC150 achieve almost 50% footprint reduction. This reduction has been made possible by the integration of the second generation of Bosch geomagnetic sensor where the 3-Axis are integrated on a single die compared to 3 separates dies for the previous generation.

The magnetic sensor still uses Bosch FlipCore technology for X/Y-Axis sensing and Hall element for Z-Axis sensing. The MEMS accelerometer is also an evolution of the one found in BMC050.

The BMC150 is a very low power (190µA) and high resolution (0.3µT) 6-axis digital compass targeted for consumer mobile applications.
