Technical values were checked against Bosch Sensortec documentation. Use the linked datasheet as the controlling source and re-check revisions before PCB release or firmware qualification.
BMA400 selection and design context
BMA400 is cataloged as a Accelerometer in the BMA400 family. Its recorded function is ultra-low-power digital triaxial accelerometer with activity recognition. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Measurement Ranges: ±2 g, ±4 g, ±8 g and ±16 g. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Digital Interface: I²C and SPI. Confirm logic levels, signaling mode, host support and required external components.
- Supply Voltage: 1.72 V to 3.6 V. Check rail compatibility, tolerance and sequencing under worst-case conditions.
- Typical Normal Current: 3.5 µA to 14.5 µA depending on configuration. Check steady-state, transient and thermal margin in the intended operating mode.
Application and qualification considerations
When evaluating this sensor, confirm measurement range, sensitivity, noise, output data rate, interface voltage, calibration needs and mechanical orientation. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.
