Product details

±240g X-axis digital accelerometer for crash and event sensing

The MMA5224AKWR2: Its ±240g acceleration range and 2 LSB/g digital sensitivity via SPI output make it suited for high-G event detection — airbag deployment, crash recording, or impact monitoring — without an external ADC.

Supply and interface — single-rail automotive integration

The device runs from a single 4.2V to 17V supply, covering the automotive battery range from cold-crank to load-dump without an external pre-regulator. Digital SPI output simplifies connection to an ECU or sensor-fusion MCU — the 16-QFN (6x6 mm) exposed-pad package provides a low-inductance ground return for the high-G sense element.

RoHS3 compliant and AEC-Q100 qualified, the part carries the documentation expected for automotive PPAP submissions.

Frequently asked questions

What is the difference between MMA5224AKWR2 and MMA5212AKWR2?

Both are X-axis digital accelerometers in the same 16-QFN package with SPI output and the same supply range. The MMA5224AKWR2 covers ±240g with 2 LSB/g sensitivity, while the MMA5212AKWR2 covers ±120g with 4 LSB/g — the 5224 doubles the range at half the sensitivity. If your application requires ±240g, the 5224 is the correct fit; the 5212 is a lower-G alternative.
