Bosch’s BMA400 Triaxial Accelerometers, Now Available from Mouser Electronics, Slash Current Consumption by 10x

Mouser Electronics, Inc., the authorized global distributor with the newest semiconductors and electronic components, is now stocking the ultra-low power BMA400 triaxial accelerometers from Bosch. Offering an industry-leading balance of high performance and low power consumption, the CES 2018 award-winning BMA400 accelerometers draw ten times less current than similar acceleration sensors. Suitable for devices requiring always-on battery systems, the BMA400 accelerometers are ideal for Internet of Things (IoT) and wearables applications.

The Bosch BMA400 triaxial accelerometers, available from Mouser Electronics, detect tilt, orientation and tap/double tap, and integrate a plug-and-play, activity-recognizing step counter. The accelerometers feature an output data rate (ODR) of 12.5 Hz to 800 Hz and low pass filters down to 3.2 µA with a selectable bandwidth of 0.48×ODR or 0.24×ODR. The devices have a supply voltage range of 1.71 V to 3.6 V and a 12-bit digital resolution. The BMA400 accelerometers are highly configurable with regard to noise performance and current consumption, allowing designers to easily integrate the devices into always-on low-power systems.

The 2.0 mm × 2.0 mm × 0.95 mm BMA400 triaxial accelerometers are ideal for wearable devices — facilitating functions like activity tracking and step counting in fitness bands and smartwatches — as well as smart home applications like indoor climate systems and security systems. Able to detect the difference between random vibrations and emergency situations like broken glass, the high-performance accelerometers help to avoid false alarms. Bosch’s low-power BMA400 accelerometers can also be used for predictive maintenance and package tracking in industrial applications.
