Rohm and UAES sign long-term SiC deal
Rohm and United Automotive Electronic Systems (UAES), a Tier 1 automotive supplier in China, have recently entered into a long-term supply agreement for SiC power devices.
Since 2015, Rohm and UAES have been collaborating and carrying out detailed technical exchanges on automotive applications utilising SiC power devices. This partnership deepened in 2020 with the establishment of the SiC Joint Research Institute at the UAES headquarters in Shanghai, China. And in 2021 Rohm’s advanced SiC power devices and peripheral components were highly evaluated by UAES, resulting in Rohm being selected as a preferred supplier.
The close long-standing technical partnership has led to the production and adoption of numerous automotive products equipped with Rohm SiCs, such as onboard chargers and inverters for electric vehicles. SiC power devices play a crucial role in enhancing the efficiency and performance of a variety of systems, contributing to extending the cruising range and reducing battery size.
This long-term supply agreement ensures UAES sufficient access to SiC power devices to meet the growing demand for SiC-based inverter modules, which have been supplied to customers since November 2023. Going forward, both companies will deepen their collaboration, contributing to technological innovation in the automotive sector by accelerating the development of cutting-edge SiC power solutions for EVs.
Guo Xiaolu, deputy general manager, UAS said: "Choosing Rohm as our long-term supplier of SiC chips guarantees a stable supply for future mass production. We appreciate Rohm’s past efforts and look forward to building a long-term collaborative relationship, with this agreement serving as a new starting point."
Tsuguki Noma, corporate officer and director of the Power Device Business Unit, Rohm said: "We believe that by working together, both companies can provide cutting-edge, high performance, high quality automotive applications. Moving forward, we will continue to drive technological innovation in electric vehicles together with UAES by offering power solutions centred on SiC."
