ROHM announced that Telechips, a significant fabless semiconductor manufacturer for automotive applications with its headquarters located in Pangyo, South Korea, has adopted its PMICs in power reference designs centered on the next-generation cockpit SoCs “Dolphin3” (REF67003) and “Dolphin5” (REF67005).
These designs are expected to go into mass production in 2025 and are meant to be used within the cockpits of European automakers.
Since 2021, the duo is said to have maintained a close working relationship from the very beginning of SoC chip design through technical exchanges. The integration of ROHM’s power supply solutions into Telechips’ power supply reference designs is the first step towards accomplishing this objective.
By integrating DrMOS and sub-PMICs with the primary PMIC for SoCs, these technologies facilitate the construction of different models.
The BD96801Qxx-C main PMIC for SoCs is part of the Dolphin3 application processor (AP) power reference architecture for infotainment applications. Similar to this, the Dolphin5 AP power reference design, created for next-generation digital cockpits, enhances overall system efficiency and reliability by combining the BD96805Qxx-C and BD96811Fxx-C major PMICs for SoC with the BD96806Qxx-C sub-PMIC for SoC.
PMICs For Modern Cockpits
As automotive applications become more multipurpose, modern cockpits are outfitted with several displays, including infotainment systems and instrument clusters. Power ICs like PMICs must be able to withstand high currents while retaining good efficiency as the computing power needed for automotive SoCs rises. Simultaneously, manufacturers need adaptable solutions that can handle many vehicle models and types with little circuit alteration. When combined with a sub-PMIC or DrMOS, ROHM SoC PMICs’ great operating efficiency and inbuilt memory (One Time Programmable ROM) enable compatibility with high currents and allow for sequence control and specific output voltage settings.
Moonsoo Kim, Senior Vice President and Head of System Semiconductor R&D Center, Telechips Inc.
“Telechips offers reference designs and core technologies centered around automotive SoCs for next-generation ADAS and cockpit applications. We are pleased to have developed a power reference design that supports the advanced features and larger displays found in next-generation cockpits by utilizing power solutions from ROHM, a global semiconductor manufacturer. Leveraging ROHM’s power supply 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, Corporate Officer and Director of the LSI Business Unit, ROHM Co., Ltd.
“We are pleased that our power reference 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 current consumption. ROHM SoC PMICs meet the high current demands of next-generation cockpits by adding a DrMOS or sub-PMIC in the stage after the main PMIC. This setup achieves high efficiency operation that contributes to lower power consumption. Going forward, ROHM will continue our partnership with Telechips to deepen our understanding of next-generation cockpits and ADAS, driving further evolution in the automotive sector through rapid product development.”
