Airbag Systems
Airbag systems increase passenger safety in all vehicles from small city cars to luxury SUVs. 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 block diagram above illustrates the application system based on ST products, starting from the sensor interface, power supply, and microcontroller up to squib drivers.
