SMG102
Angular rate sensor for rollover sensing in airbag ECUs
Application & Technical Summary
The SMG102 is a single-axis (Ωx) gyroscope (gyro) for rollover applications.
The SMG102 communicates via a digital 16-bit SPI interface. Particularly in combination with the SMB200 low-g accelerometer, it becomes an ideal sensor combination for a complete roll-over system. The sensor detects the chassis roll rate during a rollover event.
Product benefits
- Slow on-chip offset regulation
- Full self testing capability
- Continous signal monitoring
- RoHS compliant
Target application
- Rollover sensing
reliable operation
