NOVOSENSE Microelectronics announced that two highly integrated ICs—an isolated sensing IC and a logic ASC IC—developed in close collaboration with Inovance Automotive, a leading supplier of intelligent electric vehicle components and solutions, have entered mass production on Inovance Automotive’s next-generation electric drive (e-drive) platform. The customized IC solutions offer higher integration and optimized performance, supporting the ongoing shift toward more integrated electric drive systems while enabling designs that meet increasingly stringent functional safety requirements.
Conventional discrete electric drive designs rely on widely distributed components and complex wiring, often resulting in larger system size, higher power losses, slower response, and constrained reliability. As electric vehicles continue to demand longer driving range and higher output power, electric drive architectures are moving rapidly toward multi-in-one and highly integrated designs. In this context, semiconductor solutions must deliver greater functional integration while maintaining accuracy, reliability, and functional safety margins within limited space, without constraining system-level design flexibility.
Building on more than a decade of experience in motor controller system architectures and functional safety, Inovance Automotive proactively defined the key functional and performance requirements for the isolated sensing IC and logic ASC IC at an early stage of development. In response to these requirements, NOVOSENSE integrated high-voltage LDO, isolated sensing amplifier, and isolated comparator into a single isolated sensing IC. This integration significantly reduces external component while enabling high-precision isolated voltage sensing, fast OV/UV protection, and more compact electric drive designs.
The customized logic ASC IC further integrates multiple logic functions and supports frequency detection, enabling centralized handling of interface-related logic. This approach simplifies interface design, improves overall system integration, and supports more compact inverter layouts. At the same time, it helps reduce BOM cost and provides a solid foundation for optimizing functional safety architectures in electric drive and traction inverter systems.
By replacing mature discrete circuits with integrated IC solutions, the collaboration delivers clear system-level benefits.
Simplified architectures and fewer components reduce potential failure points and improve overall product robustness.
Higher integration lowers PCB area requirements, creating additional headroom for increased power density.
Standardized IC solutions also streamline development by reducing design and validation effort, helping shorten development cycles and accelerate time-to-market.
"Electric drive systems are entering a phase where higher integration is becoming essential, and progress at the chip level increasingly translates into system-level advantages," said Zheng Chao, Director of the R&D Center at Inovance Automotive. "This collaboration combines our strengths in electric drive systems with NOVOSENSE’s expertise in automotive semiconductors. More importantly, it reflects an important capability upgrade for Inovance Automotive—we are not only developing high-performance power electronics products, but also participating from the outset in defining system architectures and core chips. We look forward to continuing our work with NOVOSENSE to shape next-generation electric drive platforms and deliver more competitive system solutions to OEMs."
"NOVOSENSE and Inovance Automotive have established a strong foundation for collaboration," said Ye Jian, Product Line Director at NOVOSENSE. "This project demonstrates both our customer's confidence in our technology and our application-driven approach to innovation. By drawing on our long-standing expertise in isolation and interface technologies, we will continue to deliver high-precision, high-performance, and high-reliability IC solutions to support Inovance Automotive's next-generation electric drive platforms."
NOVOSENSE's Isolation+ portfolio covers digital isolator, isolated sensing, isolated driver, isolated power, and isolated interface, with cumulative shipments exceeding two billion units as of October 2025. The company also offers a broad automotive interface portfolio—including CAN, LIN, SerDes, logic ICs, and level shifters—providing customers with one-stop automotive-grade isolation and interface solutions. Across the new energy vehicle electrical system, NOVOSENSE works with hundreds of component suppliers, delivering semiconductor solutions for traction inverter, onboard charger (OBC), DC/DC converter, and battery management system (BMS), spanning sensor, signal chain, power management IC, and MCU.
