Product Overview

The BMA580 is an advanced, ultra-small, triaxial high-performance low-g accelerometer with digital interfaces. Designed for low-power and demanding consumer electronics applications, it integrates a 16-bit digital accelerometer with configurable ranges (2g, 4g, 8g, 16g) and an 8-bit digital temperature sensor. Its compact size, multiple digital interface options (SPI, I3C, IC), ultra-low current consumption, and integrated power management unit make it ideal for a wide range of applications. Advanced features include on-chip interrupt engines for always-on applications like activity, action, and gesture recognition (e.g., single, double, triple tap detection), and a Voice Activity Detection (VAD) feature for hearables.

Product Attributes

  • Brand: Bosch Sensortec
  • Package Type: Wafer Level Chip Scale Package (WLCSP)
  • Certifications: RoHS compliant, halogen and lead free
