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 on cost effectiveness (low-end vehicles), system complexity (advanced features and increasing number of squibs and satellites) and 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.
