BOS1921 delivers the third generation of haptic feedback to modern vehicles with ultra-low latency (<5mS), high-definition haptics and fully customizable profiles for enhanced driver experience and safety. The integration of force sensing also enables multi-function control. For example, a single solid-state button can be used for multiple infotainment menu controls. A small, compact footprint is enabled by our QFN package with wettable flanks for industry-standard reliability. The BOS1921 is designed to meet the rigorous demands of automotive environments, ensuring long-lasting performance and consistent haptic feedback even under harsh conditions.

To prototype solid-state steering wheel interfaces, we recommend the BOS1921-KIT. This development platform allows you to instantly design multi-effect buttons that provide distinct, context-aware feedback to the driver. It empowers engineers to program complex tactile effects—such as transforming a static arrow pad into a tactile scrolling wheel—demonstrating a level of versatility that LRA solutions cannot match. Leveraging the BOS1921’s <5ms latency and integrated force sensing, the kit lets you calibrate precise, safe, and intuitive feedback profiles on your desk before committing to a final mechanical design.
