Guangdong Huaguan Semiconductor Co., Ltd. was established in 2011. It is a quasi-high-tech enterprise specializing in the research and development, packaging, testing and sales of semiconductor devices. The company has an internationally advanced level of semiconductor discrete devices and integrated circuit packaging and testing production lines, and a technical team with rich experience in the design, packaging and testing of semiconductor devices. It has established long-term strategic cooperative relations with first-class companies in the same industry, and has formed a professional technical development team to engage in the development of new products and new technologies. The company's R&D project products include power management, operational amplifiers, audio amplifiers, interfaces and drivers, logic devices, memory, time base and clock, data acquisition, MOSFT and special circuits, which are mainly used in automotive electronics, instrumentation, network communications, industrial automation, LED lighting, switching power supplies, smart home appliances, gold card projects, smart transportation and other fields. Huaguan products are positioned as high-end quality, and have been well received by users in recent years. It is currently a high-end quality brand in the industry; HGSEMI&HGC is Huaguan's own brand. The establishment of an independent brand is more conducive to our service to customers, promoting the development of the company, and becoming a leading manufacturer in China's semiconductor industry.
