ROHM and Telechips have maintained technical exchanges since 2021, fostering a close collaborative relationship from the early stages of SoC chip design. As a first step toward achieving this goal, ROHM's power supply solutions have been integrated into Telechips' reference power supply designs. These solutions support the development of various models by combining sub-PMICs and DrMOS with the main PMIC for SoCs.

For infotainment applications, the Dolphin3 application processor (AP) power supply reference design includes the BD96801Qxx-C for SoCs. Similarly, the Dolphin5 AP power supply reference design, developed for next-generation digital cockpits, combines the BD96805Qxx-C and BD96811Fxx-C for SoCs with the BD96806Qxx-C for SoCs, improving overall system efficiency and reliability.

Modern dashboards are equipped with multiple displays, such as instrument clusters and infotainment systems, and every automotive application is becoming increasingly multifunctional. As the processing power required for automotive SoCs increases, power integrated circuits, such as PMICs, must be able to handle high currents while maintaining high efficiency. At the same time, manufacturers need flexible solutions that can be adapted to different vehicle types and model variations with minimal circuit modifications. ROHM's PMIC SoCs address these challenges with high-efficiency operation and an internal memory (One Time Programmable ROM) that allows for customized output voltage adjustments and sequencing control, enabling compatibility with large currents when paired with a sub-PMIC or DrMOS.

Moonsoo Kim,
Senior Vice President and Head of the System Semiconductor R&D Center, Telechips Inc., said,
“Telechips offers reference designs and core technologies focused on automotive SoCs for next-generation ADAS and cockpit applications. We are pleased to have developed a power supply reference design that supports the advanced features and larger displays found in next-generation cockpits using power solutions from ROHM, a global semiconductor manufacturer. The use of ROHM power solutions allows these reference designs to achieve advanced functionality while maintaining low power consumption. ROHM power solutions are highly scalable, so we look forward to future model expansions and continued collaboration.”

Sumihiro Takashima,
Director of the LSI Business Unit at ROHM Co.
Ltd., said, “We are pleased that our reference power supply designs have been adopted by Telechips, a company with a strong track record in automotive SoCs. As ADAS continues to evolve and cockpits become more multifunctional, power supply ICs must handle larger currents while minimizing power consumption. ROHM’s PMIC SoCs meet the high current demands of next-generation cockpits by adding a DrMOS or sub-PMIC downstream of the main PMIC. This configuration achieves high-efficiency operation, which helps reduce power consumption. Looking ahead, ROHM will continue its collaboration with Telechips to deepen its understanding of next-generation cockpits and ADAS, driving further evolution in the automotive industry through rapid product development.”

Telechips' Dolphin Series SoCs:
The Dolphin series comprises automotive SoCs tailored for in-vehicle infotainment (IVI), advanced driver assistance systems (ADAS), and autonomous driving (AD) applications. The Dolphin3 supports up to four displays and eight cameras in the vehicle, while the Dolphin5 allows up to five displays and eight cameras, making it well-suited as a SoC for increasingly multifunctional next-generation cockpits. Telechips focuses on expanding the Dolphin series of application processors (APs) for in-car infotainment, with models such as the Dolphin+, Dolphin3, and Dolphin5, leveraging its world-renowned technical expertise cultivated over many years.
