Product details

What this part is and where it fits

The NXP MMA5212AKWR2 is a single-axis (X-axis) digital accelerometer from the Xtrinsic family, designed for high-g inertial sensing in automotive safety systems. It measures acceleration up to ±120g and communicates over a digital SPI interface, with an output sensitivity of 4 LSB/g. The part is qualified to AEC-Q100 and operates across the full automotive temperature range of -40°C to 125°C, making it suitable for under-hood and cabin safety applications such as electronic stability control, airbag deployment sensing, and crash impact detection.

Supply voltage and power rail fit

The supply voltage range of 4.2V to 17V covers both regulated 5V rails and direct automotive battery voltage. This eliminates the need for an additional LDO in many designs, saving board space and BOM cost. The wide range also provides headroom for load-dump transients on unregulated supply lines, a common requirement in automotive ECU designs.

Lifecycle and sourcing reality

It is ROHS3 compliant.

Frequently asked questions

Does the MMA5212AKWR2 support the PSI5 interface?

Yes, the part is described as an Xtrinsic PSI5 inertial sensor, indicating it supports the PSI5 peripheral sensor interface standard commonly used in automotive safety systems.

Is the MMA5212AKWR2 a direct replacement for other MMA52xx series parts?

The MMA5212AKWR2 shares the same 16-QFN package and SPI interface as other MMA52xx family members, but the ±120g range and X-axis-only output are specific to this variant. Verify the acceleration range and axis count against your application before substituting.

What is the acceleration range and output type of the MMA5212AKWR2?

It measures ±120g on the X-axis and outputs digital data via SPI with a sensitivity of 4 LSB/g.
