About Miartech

Miartech (Shanghai) Microelectronics Co., Ltd. operates as a fabless semiconductor company, specializing in the design and development of high-performance, mixed-signal integrated circuits. Founded in July 2004 by Dr. Quan Xiong, the company established its headquarters in the Zhangjiang Hi-Tech Park in Shanghai. Dr. Xiong, who serves as Chairman and CEO, possesses an extensive academic and professional background in physics and microelectronics, with degrees from Tsinghua University and Brown University, postdoctoral work at MIT, and over a decade of experience in senior engineering and management roles at companies like AMD and LSI Logic before co-founding Miartech.

The company's core business revolves around providing powerline communication (PLC) chipsets and related energy management solutions. These products are designed for application in smart grids, smart cities, energy-efficient buildings, and smart homes. Miartech's business model targets global equipment manufacturers, particularly those in the smart meter industry, by supplying them with the necessary integrated circuits for their devices. Its primary offering, the Mi-series of PLC chips, enables networking between electrical, sensory, and control equipment by using existing low-voltage power lines as the communication medium, which provides a low-cost method for building a "Power IoT" network. These chips have seen significant application in smart meter and electricity information acquisition systems across more than 10 provinces within China's national grid.

Miartech secured a Series A funding round of $6 million in April 2006 from investors including DFJ DragonFund and Element Partners. This was followed by a Series B round of $10 million in November 2011 from Intel Capital, Tsing Capital, and DFJ DragonFund China. The company gained recognition for its work, receiving an award as a key enterprise in Shanghai's smart grid industry in March 2011 and was later named one of China's Top 20 Clean Technology Businesses. Public records indicate the company's registration was revoked in June 2022.
