Bosch Automotive ICs

Whether detecting objects through radar, managing power in electrified drivetrains, or triggering safety functions such as airbags: Automotive ICs (integrated circuits) are essential to how vehicles sense and react to the world around them, especially under extremely demanding circumstances inside a vehicle. By combining this automotive-grade robustness with deep vehicle system expertise, global manufacturing strength, and decades of semiconductor experience with several hundred IC products in the market, Bosch’s business unit Integrated Circuits is the trusted partner for the automotive industry, supporting OEMs and Tier-1 suppliers worldwide.

Most drivers never see them, yet ICs enable many functions that define modern vehicles. Their role is becoming more and more important as vehicles evolve further into complex electronic systems on wheels. Automated and assisted driving functions need precise sensing and fast data processing, while new E/E architectures require reliable communication and real-time control concepts. At the same time, every component must meet strict automotive requirements over long lifecycles and under demanding conditions such as heat, cold, vibration, and electrical stress. They must perform reliably in safety-critical situations and support functions where failure is not an option.

As vehicle electronics continue to evolve, demand for mixed-signal ICs is growing. Electrified powertrains, emerging 48V power networks, advanced sensing functions, and the transition toward zonal and centralized compute architectures all require highly robust semiconductor solutions. At the same time, vehicle manufacturers must continue to support existing electronic architectures, creating a need for IC portfolios that bridge current and next-generation vehicle platforms. Mixed-signal ICs play a key role in this transformation by enabling sensing, actuation, power management, safety, and communication functions throughout the vehicle.

Developing automotive ICs for these applications requires more than semiconductor expertise alone. Bosch combines IC design capabilities with deep vehicle system knowledge across domains such as ADAS, safety, electrification, and E/E architectures (48V systems). This system-level perspective ensures that ICs meet real-world automotive requirements and integrate effectively into the overall vehicle architecture. Bosch ICs are backed by a global manufacturing footprint, a strong R&D network, and long-term supply capabilities.
