Looking for scalable automotive airbag ICs for passive safety systems?
STMicroelectronics offers a comprehensive portfolio of analog and mixed-signal ICs for automotive airbag and passive safety systems, helping carmakers and Tier 1 suppliers address a wide range of platform requirements with greater flexibility and efficiency. From cost-optimized entry-level vehicles to high-end centralized safety domain controllers, our integrated all-in-one airbag system-on-chip solutions and scalable airbag extension ICs are designed to support the latest ISO 26262 functional safety and ASIL targets.
The ST airbag IC portfolio, including L9678P, L9679P, and L9680, combines key building blocks for robust and scalable passive safety system architectures:
- High-efficiency power supply modules with boost and buck converters and accurate ADC voltage references
- Configurable squib drivers with programmable deployment profiles and extensive diagnostics
- PSI5 satellite sensor interfaces for front, side, and curtain airbags
- Hall-effect and resistive sensor interfaces for seat occupancy, buckle, and position sensing
- Embedded system diagnostics and fault handling for higher safety and reliability
This highly scalable approach helps reduce BoM, simplify PCB layout, and accelerate the design of passive safety system ACU (airbag control unit) architectures across multiple vehicle platforms.
