ROHM has developed a configurable power supply solution that combines its BD968xx?C Series PMICs with the BD96340MFF?C DrMOS, targeting automotive SoCs used in applications such as ADAS, driver monitoring systems, and sensing cameras.
As automotive SoCs continue to demand more performance, driven by advances in ADAS, richer in-vehicle camera functions, and ECU integration, the industry is moving quickly toward domain architectures built around domain controllers.
That shift has raised the bar for power supply design, which now needs to support low-voltage, high-current operation, advanced power sequencing, and high reliability.
Traditional power supply architectures often need heavy customization to match the requirements of different SoC vendors and generations. In many cases, that means redesigns every time a model is updated, adding time and increasing verification effort.
To help solve this, ROHM created a solution based on a configurable design concept that can adapt more easily to a wide range of SoC power requirements.
The result is a scalable power supply platform that can support everything from low-end to high-end SoCs by combining main configurable PMICs, sub PMICs, and DrMOS devices as needed. This approach helps reduce development effort when expanding platforms, while improving power efficiency and making design reuse easier.
All PMICs support a 2.7 V to 5.5 V input range. The BD96803Qxx?C and BD96811Fxx?C are optimized for standalone use with low-end SoCs, while the BD96805Qxx?C and BD96806Qxx?C, when paired with the BD96340MFF?C DrMOS, are designed to handle the low-voltage, high-current demands of higher-performance SoCs.
The PMICs come in wettable flank QFN packages, and the DrMOS is packaged in a flip-chip QFN format. All devices are AEC?Q100 qualified, making them suitable for demanding in-vehicle applications.
Mass production has already begun.
