Combined inertial sensor for non-safety relevant applications

Application & Technical Summary


The SMI130 detects acceleration and angular rates in three perpendicular axes (axyz, Ωxyz). It allows tilt, motion, vibration, or shock sensing regardless of the sensor mounting orientation.

The SMI130 contains a digital 16-bit gyroscope (gyro) and a digital 12-bit accelerator with different measurement ranges. The sensor combines knowledge from consumer and automotive electronics. Numerous programming options, a low signal noise and a small footprint make the SMI130 a highly versatile and easily applied combined inertial sensor for non-safety automotive applications.

Product benefits

  • Extremely flexible application options
  • Cost-effective
  • Small footprint
  • Low power consumption – even at system level
  • Billion-fold applied technology (due to CE background)
  • AEC-Q100 qualification
  • RoHS compliant

Target applications:

  • Navigation (dead reckoning) and eCall services
  • Vehicle dynamics data logging
  • Car alarm


through 3 power-saving modes, which give a very low power consumption
