A few days ago, in an interview with Echo Zhao, the main analyst of EE Times magazine, Nasser Microelectronics CEO Wang Shengyang stated that the development strategy of Nanocore Micro Futures will be driven by 'achieve high quality import substitution' and 'innovative applications'. ' for the two major directions.
When talking about the layout and development direction of the product line, Wang Zong stated: 'Naxin Micro has always focused on the mixed-signal chip design in the signal chain field. At present, we have two major product lines: digital isolation chips and sensors; among them, sensors The product line focuses on pressure sensors, inertial sensors, temperature sensors, oxygen and nitrogen-oxygen sensors, etc. The main markets are industrial, automotive, and other innovative applications. ' With respect to the planning of digital isolation for this new product line, Wang The general said: 'We have invested more than two years in the field of digital isolation. We have already developed two channels, three channels, four channels, bidirectional I2C and other digital isolation chips. In the future, we will release isolation 485 in succession. CAN, isolated ADC and other rich products to satisfy various applications.
'Isolation chip is actually not a new product, but its application range is very broad. Basically, all the signal transmission fields between high voltage and low voltage need isolation technology.' When isolating the chip field is based on what considerations, Wang Zong said: 'Traditional isolation mainly uses optocoupler technology, optocoupler isolation has developed into a very mature market, market capacity is about 10 billion channels a year. We observe In the last two years, there has been a new kind of technology that is slowly replacing the market share of optocouplers. That is digital isolation. This emerging market is currently mainly owned by several large international companies such as ADI, TI, and Silcon Labs. Since digital segregation is a relatively high-end area, there has been no domestic manufacturers involved in this area before. Currently, digital segregation will have a market share of about 2-3 billion channels per year, and this data is growing. It is such a huge Market space and opportunities, we invested about two years of research and development, and recently successfully launched dual-channel, three-channel, four-channel and other digital isolated chip products. . '
Regarding the development trend of the digital isolation market, Wang always judges that the market should continue to grow in the future. 'As far as optocoupler is concerned, digital isolation has very obvious advantages in terms of reliability, power consumption, size, and integration. Nowadays, it is hot. The new energy vehicle market will drastically promote the rise of the digital isolation market. Because the new energy vehicles use 300-400V high-voltage batteries, high-voltage batteries and low-voltage control signals need to be isolated between the high-power motor drive and control signals Also need to be isolated. Therefore, with the further popularization of new energy vehicles, the digital isolator market will be further favored.
As the first domestic manufacturer to successfully mass-produce digital isolation chips, NSN has attached great importance to the reliability performance of its products. Wang introduced: 'We have conducted comprehensive tests on our products. We have EMC performance and anti-common mode interference performance. With respect to various reliability parameters such as ESD performance, isolation performance, etc., our products are basically at the leading edge compared with the products of foreign manufacturers. Therefore, we are very confident in the products and we hope to make domestically produced chips. Promote high-quality import substitution in high-end application areas.
