SMG810

Angular rate sensor for rollover sensing in airbag ECUs

Application & Technical Summary

SMG810

SMG810 is a single axis (Ωx) gyroscope (gyro) for rollover applications. It s derived from the successful SMI8xy inertial sensor familiy and detects the chassis roll rate during a rollover event. The sensor communicates via a digital 16-bit SPI interface.

Product benefits

  • Excellent vibration robustness and offset stability
  • Developed for systems with requirements up to ASIL D

Target applications:

  • Roll-over sensing

reliable operation

due to excellent vibration resistance
