BMA456
Basic Information
| Part Number | BMA456 |
|---|---|
| Manufacturer | Robert Bosch GmbH |
| Category | Motion Sensors – Accelerometers |
| Description | Digital Triaxial Accelerometer, I2C/SPI Interface, Low Power, LGA-12 Package |
Product Overview
The BMA456 is a high-performance, ultra-low-power digital triaxial accelerometer designed for wearable devices, hearables, and battery-powered consumer electronics. It features integrated intelligence for motion detection, wake-up functions, tap/double-tap recognition, and activity classification, enabling efficient and autonomous operation without continuous microcontroller intervention. With a compact form factor, wide measurement range, and high sensitivity, this sensor delivers accurate acceleration data while maintaining extremely low power consumption. The device supports both I2C and SPI communication interfaces and is housed in a miniature LGA-12 package, making it ideal for space-constrained portable designs requiring reliable motion sensing and gesture detection.
