ROHM Certified as a Preferred Supplier for UAES

ROHM has now been recognized as a preferred supplier of SiC power solutions by United Automotive Electronic Systems Co., Ltd., (UAES), a Chinese Tier 1 comprehensive automotive manufacturer.

ROHMROHM and UAES have been collaborating and carrying out detailed technical exchanges on the development of automotive applications utilizing SiC power devices since 2015.

Guo Xiaolu, Deputy General Manager, United Automotive Electronic Systems Co., Ltd., said,” We have been conducting ongoing technical exchanges with ROHM, a leader in SiC power devices. The high rating that ROHM devices and peripheral solution proposals have received has led to ROHM being selected as a preferred supplier. For us at UAES, vehicle applications utilizing SiC are an important business that is about to go into full swing, and we have now entered a concrete stage of mass production of SiC-equipped inverters and other products. We would like to thank ROHM for their previous efforts and look forward to building a long-term collaborative relationship using this certification as a new start.”

Kazuhide Ino, Managing Executive Officer, CSO and Director of Accounting & Finance Headquarters, ROHM Co., Ltd. said, “We are very appreciative to have received this recognition by UAES, the largest Tier 1 manufacturer in China. As the automotive market moves quickly towards electrification, we see an important opportunity to help UAES develop advanced applications that meet customer needs. ROHM offers a broad range of products in addition to SiC, including IPMs, IPDs, gate drivers, and LED drivers that are ideal for onboard inverters and chargers. Going forward, we look forward to deepening our relationship with UAES and promoting the development of a wide range of products utilizing ROHM’s cutting-edge technologies that will contribute to the further evolution of electric vehicles.”

In 2020 ROHM established a joint SiC technology laboratory at UAES headquarters (Shanghai, China) to strengthen cooperation on the development of innovative power solutions centered on SiC, and mass production of many automotive products equipped with ROHM SiC power devices is already underway, such as onboard chargers for electric vehicles.

More recently, ROHM’s industry-leading SiC power device performance along with power solutions that include peripheral components was highly evaluated, resulting in ROHM being selected as the first preferred supplier in this field.

ROHM SiC power devices are also being used in inverter modules currently being developed by UAES to extend the cruising range of electric vehicles and reduce battery size.
