Ultra-low power accelerometer for wearables and IoT

Ultra-low power accelerometer for wearables and IoT

By eeNews Europe

The BMA400 combines ultra-low power consumption, outstanding performance and advanced features, such as a built-in step counter that uses only 4 µA. The BMA400’s continuous measurement capabilities and always-defined bandwidth make it an ideal choice for hassle-free usage. Its ultra-low power consumption means replacing batteries is needed less frequently.

Through the internal voltage regulator, the BMA400 offers stable performance over a wide input voltage range. The device s flexible, with tuning for power consumption, noise and ODR (output data rate). It has a current consumption of 14 μA at highest performance, continuous measurement and a noise density of 180 μg/√Hz. This drops to just 1 μA and below in the device’s ultra-low power self-wake-up mode. The small size of only 2.0 x 2.0 x 0.95 mm³ and the integrated plug-and-play step counter make the BMA400 easy to design into new types of wearables.
