BMA456 with hearable feature set Intelligent, triaxial accelerometer
■The BMA456 is an ultra-small, triaxial, low-g and high-performance accelerometer with digital interfaces, aiming for low-power hearable applications. Featuring 16-bit digital resolution and several smart features, the BMA456 allows low-noise measurement of acceleration in three perpendicular axes and thus senses single/double/triple tap and enables plug 'n' play step counting especially optimized for hearable devices. In addition, BMA456 enables in-eai/out-of-ear detection.
■The superior temperature behaviour of BMA456 facilitates accurate measurements over changing temperatures. Thanks to the low height of only 0.65 mm, manufacturers can flexibly place the sensor and minimize the design of the hearable devices.
●SENSOR FEATURES
■BMA456 is the industry's only accelerometer with nmw and optim ized features for hearable devices and headphones integrated in one sensor. The BMA456 integrates a m ultitude of features like triple tap, step counting and activity recognition that that facilitate the usage and enhance the user experience of hearable devices. The plug'n' play step counter and activity recognition feature is optimized for hearable positions.
■In the low-power mode the power consumption is reduced to 14 μA for standard use cases. The integrated motion/no-motion detection automatically switches the sensor to the ultra-low power mode with a power consumption of only 6 μA. Motion autom atically triggers a wake-up function. This fulfills the power consumption requirements for hearable devices. In addition, a high-performance measurement mode with low pass filters is available to make the BMA456 robust to vibrations and aliasing. The default parameter set of the BMA456 features is highly configurable in order to give the designer full flexibility when integrating the sensor into the system.
