Product Overview
The Bosch Sensortec BMI090L is a high-performance longevity Inertial Measurement Unit (IMU) designed for industrial applications requiring long lifecycles, such as robots and white goods. This 6-axis IMU integrates a 16-bit triaxial gyroscope and a 16-bit triaxial accelerometer within a compact 3 x 4.5 x 0.95 mm (16-pin) LGA package. It features a closed-loop gyro and a robust accelerometer with a built-in mechanical filter to suppress high-frequency vibrations, ensuring precise orientation and motion tracking in demanding environments. The BMI090L offers a wide acceleration measurement range (3 g to 24 g), high vibration robustness, and excellent temperature stability. Its automotive-proven gyroscope boasts a bias instability of less than 2 /h and a low temperature coefficient of offset (TCO) below 15 mdps/K. The accelerometer features a low TCO of 0.2 mg/K and low spectral noise of less than 200 g/sqrt(Hz). The device supports IC and SPI digital interfaces and includes a 1 kB FIFO for synchronized data acquisition.
