ROHM’s Scalable Power Solution for Automotive SoCs: A Game-Changer for ADAS and DMS

Is China’s new scalable power solution for automotive SoCs about to revolutionize the way we design ADAS and DMS systems?

Introduction

On May 19, 2026, semiconductor manufacturer ROHM unveiled a groundbreaking, scalable power solution for automotive System-on-Chips (SoCs). This innovative solution, combining the PMIC BD968xx-C series with DrMOS BD96340MFF-C, is specifically designed to meet the growing performance demands of Advanced Driver Assistance Systems (ADAS), Driver Monitoring Systems (DMS), and sensing cameras. This development is particularly significant as the automotive industry shifts towards a domain controller-based architecture, where low voltage, high current, and advanced power sequencing are crucial.

The Need for Scalable Power Solutions

As ADAS and DMS technologies continue to evolve, the performance requirements for automotive SoCs have increased dramatically. The transition to a domain architecture, which integrates multiple functions into a single controller, has further accelerated this trend. Traditional power solutions often require extensive customization to accommodate different SoC manufacturers and generations, leading to longer development cycles and higher validation costs.
