ROHM has introduced the adoption of its PMICs in energy reference designs targeted on the next-generation cockpit SoCs ‘Dolphin3’ (REF67003) and ‘Dolphin5’ (REF67005) by Telechips, a serious fabless semiconductor producer for automotive purposes headquartered in Pangyo, South Korea. Supposed to be used contained in the cockpits of European automakers, these designs are scheduled for mass manufacturing in 2025.
ROHM and Telechips have been engaged in technical exchanges since 2021, fostering a detailed collaborative relationship from the early levels of SoC chip design. As a primary step in reaching this purpose, ROHM’s energy provide options have been built-in into Telechips’ energy provide reference designs. These options assist various mannequin improvement by combining sub-PMICs and DrMOS with the principle PMIC for SoCs.
For infotainment purposes, the Dolphin3 software processor (AP) energy reference design consists of the BD96801Qxx-C fundamental PMIC for SoCs. Equally, the Dolphin5 AP energy reference design developed for next-generation digital cockpits combines the BD96805Qxx-C and BD96811Fxx-C fundamental PMICs for SoC with the BD96806Qxx-C sub-PMIC for SoC, enhancing total system effectivity and reliability.
Fashionable cockpits are outfitted with a number of shows, comparable to instrument clusters and infotainment methods, with every automotive software changing into more and more multifunctional. Because the processing energy required for automotive SoCs will increase, energy ICs like PMICs should be capable of assist excessive currents whereas sustaining excessive effectivity. On the similar time, producers require versatile options that may accommodate completely different car varieties and mannequin variations with minimal circuit modifications. ROHM SoC PMICs deal with these challenges with excessive effectivity operation and inside reminiscence (One Time Programmable ROM) that permits for customized output voltage settings and sequence management, enabling compatibility with massive currents when paired with a sub-PMIC or DrMOS.

Senior Vice President and Head of System Semiconductor R&D Heart, Telechips Inc.
“Telechips presents reference designs and core applied sciences centered round automotive SoCs for next-generation ADAS and cockpit purposes. We’re happy to have developed an influence reference design that helps the superior options and bigger shows present in next-generation cockpits by using energy options from ROHM, a worldwide semiconductor producer. Leveraging ROHM’s energy provide options permits these reference designs to attain superior performance whereas sustaining low energy consumption. ROHM energy options are extremely scalable, so we stay up for future mannequin expansions and continued collaboration.”
Sumihiro Takashima,
Company Officer and Director of the LSI Enterprise Unit, ROHM Co., Ltd.
“We’re happy that our energy reference designs have been adopted by Telechips, an organization with a powerful observe report in automotive SoCs. As ADAS continues to evolve and cockpits grow to be extra multifunctional, energy provide ICs should deal with bigger currents whereas minimizing present consumption. ROHM SoC PMICs meet the excessive present calls for of next-generation cockpits by including a DrMOS or sub-PMIC within the stage after the principle PMIC. This setup achieves excessive effectivity operation that contributes to decrease energy consumption. Going ahead, ROHM will proceed our partnership with Telechips to deepen our understanding of next-generation cockpits and ADAS, driving additional evolution within the automotive sector by means of fast product improvement.”
