Selectable bandwidth of 0.48×ODR or 0.24×ODR
2.0×2.0×0.95mm, suitable for wearable devices

Mouser Electronics supplies Bosch's ultra-low-power 3-axis accelerometer BMA400.

Balancing high performance and low power consumption, the BMA400 has won recognition at CES 2018 and features current consumption 1/10th that of acceleration sensors with comparable performance. It is an ideal component for devices requiring continuous battery-powered operation and can be used in IoT and wearable devices.
Bosch's BMA400 3-axis accelerometer supplied by Mouser senses tilt, orientation, tap and double tap, and combines a plug-and-play pedometer that recognizes activity. It provides a data output rate (ODR) of 12.5~800Hz and low-pass filter performance of minimum 3.2µA, with selectable bandwidth of either 0.48×ODR or 0.24×ODR. Additionally, it offers a supply voltage range of 1.71~3.6V and 12-bit digital resolution.

The BMA400 accelerometer offers high flexibility in setting noise and current consumption, allowing designers to easily integrate it into always-on low-power systems. The BMA400 3-axis accelerometer with dimensions of 2.0×2.0×0.95mm is suitable for wearable devices.

It performs functions such as activity tracking and pedometer in fitness bands and smartwatches, and is also used in smart home applications such as indoor climate systems and security systems. As a high-performance accelerometer capable of distinguishing between emergency situations like breaking glass and random vibrations, it helps prevent false alarms.

Bosch's low-power BMA400 accelerometer is also used in predictive maintenance and package tracking in industrial applications.
