ROHM Co., Ltd. (Headquarters: Kyoto, Japan) has developed a new power solution that combines its PMIC (Power Management IC) "BD968xx-C series" and DrMOS "BD96340MFF-C" for automotive SoCs (Systems-on-a-Chip) used in applications like Advanced Driver-Assistance Systems (ADAS), Driver Monitoring Systems (DMS), and sensing cameras.
This solution allows for the flexible combination of a main configurable PMIC, a sub-PMIC, and a DrMOS, depending on the SoC's application and performance requirements. This enables support for a wide spectrum of SoCs, from low-end to high-end, providing a scalable power configuration tailored to processing performance and functionality. It contributes to reducing design man-hours for new models and enhancing power efficiency. All products in this solution are compliant with the AEC-Q100 automotive reliability standard, ensuring high dependability.
The main PMIC features a necessary output voltage range and flexible power sequencing control for automotive SoC applications, adapting to the varying power requirements of different SoC manufacturers, generations, and grades. It also includes built-in monitoring and protection functions for voltage, current, and temperature, securing the high reliability and safety required in automotive use.
The main PMICs "BD96803Qxx-C" and "BD96811Fxx-C" are intended for standalone use with low-end SoCs. In contrast, the main PMIC "BD96805Qxx-C" and sub-PMIC "BD96806Qxx-C", when combined with the DrMOS "BD96340MFF-C", offer high scalability to handle the low-voltage, high-current demands of advanced SoCs.
Mass production of these new products has already commenced. For more details, customers are advised to contact their sales representative or use the inquiry form on the ROHM website.
## Development Background
In recent years, the performance of automotive SoCs has increased due to the sophistication of ADAS, advanced in-vehicle cameras, and progress in ECU integration. Concurrently, the shift towards domain architecture, driven by ECU consolidation, has expanded systems centered around domain controllers. This has created a greater demand for power supply designs that can drive SoCs with low voltage and high current, along with advanced power sequencing control and high reliability. However, conventional power supply design faced challenges, requiring custom solutions for each SoC manufacturer and generation, and necessitating circuit redesigns for model rollouts, which increased design effort and verification burdens. To address these issues, ROHM developed this power solution based on a "Configurable" design philosophy, allowing for flexible optimization by combining PMICs and DrMOS. This enables efficient power design tailored to SoC performance and use, while also accommodating future performance enhancements.
## Application Examples
- High-Power SoCs: ADAS, DMS, integrated cockpit systems, etc.
- Mid-Power SoCs: Surround-view systems, parking assist systems, etc.
- Low-Power SoCs: Sensing cameras, body control, various sensor controls, etc.
