Passive Safety : Airbag
Airbag systems are nowadays a standard in all vehicles from small city cars to luxury SUVs increasing passenger safety. To serve these different market segments, the automotive industry is focusing in three main areas:
- Cost effectiveness (low-end vehicles)
- System complexity (advanced features and increasing number of squibs and satellites)
- High reliability standards
ST is the ideal partner to achieve these goals through proprietary silicon technologies (BCD – Bipolar, CMOS, and DMOS) and a wide range of products covering full custom ICs and very flexible open-market solutions. The following block diagram illustrates the application system based on ST products, starting from the sensor interface, power supply, and microcontroller up to squib drivers.
