With its eCompass sensor family, Bosch Sensortec started a new portfolio of high precision MEMS sensors for compass applications in smartphones, navigation systems and other portable devices. Two separate sensors are integrated within the LGA package: a 3-axis magnetometer for geomagnetic field detection and a 3-axis accelerometer for tilt compensation. The integrated accelerometer features all functionalities of a standalone device.
The 6-axis BMC156 is an small and low power digital compass with a footprint of merely 2.2 x 2.2 mm² and 0.95 mm height as well as a 12 bit digital resolution. Due to its pin-compatible pin-out, it fits well on a 2 x 2mm² standard accelerometer landing pattern (BMA).
Housed in an LGA package with a footprint of 2.2 x 2.2 mm² and 0.95 mm height, BMC150 is an extremely small low power and low noise 6-axis digital compass with a 12 bit resolution.
The BMC056 is a low-power and low-noise 6-axis MEMS sensor housed in a package with a footprint of 3.0 x 3.0 mm² and 0.95 mm height and a 12 bit digital resolution.
The BMC050 is a 6-axis digital e-compass. It comes in a small LGA package with a footprint of 3.0 x 3.0 mm² and 0.95 mm height with a 10 bit digital resolution.
