ROHM PMICs Power Telechips’ Next-Generation Cockpit SoCs for European Automakers
ROHM Semiconductor has announced the integration of its Power Management ICs (PMICs) into power reference designs for Telechips’ next-generation cockpit system-on-chips (SoCs). These reference designs, supporting the Dolphin3 (REF67003) and Dolphin5 (REF67005) SoCs, are tailored for advanced automotive applications and will be implemented in vehicles from European automakers starting in 2025.
A Partnership Rooted in Collaboration
Since 2021, ROHM and Telechips have worked closely, fostering a technical partnership from the initial stages of SoC development. As part of this collaboration, ROHM’s power supply solutions have been incorporated into Telechips’ power supply reference designs, providing flexibility and scalability for diverse automotive models. By combining main PMICs with sub-PMICs and DrMOS, these solutions deliver efficient power management for Telechips’ cockpit systems.
Advanced Power Solutions for Multifunctional Cockpits
The Dolphin3 application processor (AP) power reference design incorporates ROHM’s BD96801Qxx-C main PMIC for SoCs, optimized for infotainment systems. Meanwhile, the Dolphin5 AP power reference design integrates BD96805Qxx-C and BD96811Fxx-C main PMICs with BD96806Qxx-C sub-PMICs, enhancing system efficiency and reliability for next-generation digital cockpits.
Modern automotive cockpits now feature multiple displays, such as instrument clusters and infotainment systems, each requiring significant processing power. To meet these demands, ROHM’s PMICs offer high-current support with exceptional efficiency, addressing the growing need for adaptable solutions. The inclusion of One Time Programmable ROM enables custom output voltage settings and sequence control, allowing for seamless integration across various vehicle configurations.
Driving Innovation in Automotive Technology
Telechips’ Dolphin series SoCs are designed to power advanced In-Vehicle Infotainment (IVI), Advanced Driver Assistance Systems (ADAS), and autonomous driving applications. Dolphin3 supports up to four displays and eight cameras, while Dolphin5 extends functionality to five displays and eight cameras. These capabilities make the Dolphin series ideal for the increasingly multifunctional nature of modern cockpits.
ROHM’s PMICs play a critical role in supporting these advancements by providing scalable and efficient power solutions. This technology partnership ensures that Telechips’ reference designs can accommodate the complex demands of next-generation automotive systems, while maintaining low power consumption.
