Sensing solutions for smartphones & tablets

The triaxial BMA422 is an ultra-small, low-g acceleration sensor with digital interfaces, especially aiming for low-power consumer electronics applications. Accordingly, the BMA422 accelerator is the perfect match for various use cases such as gesture recognition, advanced power management or shock and freefall detection. BMA422 is able to detect significant motion, tilt and enables plug ’n’ play step counting in smartphones and wearable devices. Furthermore, the BMA422 is optimized to fulfill Android M low-power accelerometer requirements.

Bosch Sensortec´s triaxial BMA400 is the first real ultra-low power acceleration sensor. Accordingly, the BMA400 is especially suited for wearable devices, which need a long-lasting battery lifetime. Further, it is the ideal solution for smart home applications e.g. smart indoor climate systems and smart home security systems. By distinguishing between critical situations and false signals, the new acceleration sensor avoids false alarms.

The low-power, low-noise BMM150 is a 3-axis digital geomagnetic sensor that perfectly matches the requirements of compass applications. By means of sensor data fusion software tailored to the hardware, the BMM150 provides absolute spatial orientation and motion vectors with high accuracy and dynamics. The BMM150 is also especially suited for supporting drones in accurate heading. The BMM150 can be used together with an inertial measurement unit consisting of a 3-axis accelerometer and a 3-axis gyroscope such as Bosch Sensortec’s BMI055.

The BMI323 is a general purpose, low-power Inertial Measurement Unit (IMU) that combines precise acceleration and angular rate (gyroscopic) measurement with intelligent on-chip motion-triggered interrupt features. BMI323 targets fast and accurate inertial sensing in all applications. It is an easy-to-use IMU with an integrated feature set.

The ultra-low power BMI263 is Bosch Sensortec’s first IMU which is compliant with the latest I3C standard as defined by MIPI Alliance. This 6-axis sensor combines precise acceleration and angular rate measurement data with intelligent on-chip motion-triggered interrupt features. Based on the MIPI I3CSM serial interface with two signal lines (Data SDA & Clock SDC), the BMI263 shows reduced pin count, wiring complexity, signal paths and offers consequently high-speed data transfer at very low power levels compared to the traditional I2C or SPI interfaces.

The ultra-low power BMI260 is an IMU consisting of a 16-bit tri-axial gyroscope and a 16-bit tri-axial accelerometer combining precise acceleration, angular rate measurement and intelligent on-chip motion-triggered interrupt features. This next-generation IMU provides fast, exact inertial sensing in smartphones and HMI applications. It provides highly accurate step counting, motion detection and is pin-to-pin compatible with the BMI160. Its industry’s first self-calibrating gyroscope with motionless CRT functionality compensates MEMS typical soldering drifts, ensuring post-soldering sensitivity errors down to ± 0.4%.
