The ability to detect accelerations in the order of hundreds of g is appealing for both industrial and consumer applications where inertial measurement units (IMUs) are typically employed. This presentation describes the architecture and design of an IMU with dual accelerometers, which together can detect acceleration across a wide operating range. It also covers a unique power-efficient solution that uses in-sensor computing to fuse data from both the low-g and high-g accelerometers while minimizing current consumption based on application context requirements.
