SMG810
Angular rate sensor for rollover sensing in airbag ECUs
Application & Technical Summary
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
