elevenmonthfifteenSolsticeseventeenDay,two thousand and twenty-twoThe Munich South China Electronics Exhibition was grandly held at the Shenzhen International Convention and Exhibition Center (Bao'an New Hall). This year's Munich South China Electronics Exhibition“Integrated innovation”Focusing on the application of cutting-edge technology in the industry, we comprehensively showcase new products, models, and formats in the electronics industry. On the occasion of the exhibition, Master Xin interviewed several excellent companies in the semiconductor industry chain in China, and specially launched“Come here with admiration·Zhen Hao”Special report.
&Nbsp;
This article is an exclusive interview with Master XinJiao Liansheng, Automotive Marketing Director of Shanghai Shuming Semiconductor Co., Ltd. (hereinafter referred to as "Shuming Semiconductor")Interview transcripts.
&Nbsp;
Shuming Semiconductor was founded intwo thousand and thirteenIn, we focused on developing high-performance and highly reliable analog chips and providing overall solutions for the system.The company's core technology andIPThey are all self-developed and possess independent intellectual property rights, obtainingISO9001:20fifteenAnd certified by the national intellectual property system. The company's products cover driver chips, power management and intelligent photovoltaic chips, interface and signal chain chips, and several products have successively obtained:ULSafety certificationCQCCertificationVDESafety certification and passingAEC-Q100Vehicle specification level reliability standard. At present, the product has been widely used in electric vehicles, new energy optical storage and charging, and pan industrial fields.
&Nbsp;
01Please briefly introduce your company's product line. What exhibits did your company bring to this electronic exhibition.
&Nbsp;
Shuming Semiconductor Jiao Liansheng:Suming Semiconductor mainly has three product lines: driver, interface and signal chain, power management, and intelligent photovoltaic.
&Nbsp;
The first type of driver chips mainly include isolated drivers, non isolated drivers, andVCSELDrivers and other products.
&Nbsp;
The second type is that the interface and signal chain chips are mainly non isolated and isolatedCANandfour hundred and eighty-fiveProducts such as interfaces, digital isolators, and isolation sampling.
&Nbsp;
The third category is power management and intelligent photovoltaic chips, mainly includingTECController, charge pump, switching power supply,LEDDrive and intelligent photovoltaic optimization and shutdown products. Currently, we have delivered in large quantities in the marketTECController, negative pressure charge pump, and switching power supply products.
&Nbsp;
The products we bring to this exhibition are divided into two categories: one is that the company has already matured for mass productionProducts that have been widely recognized and applied by customers in the entire market. For example, isolated drive productsSLMi823xSelected by customers in the energy conversion category due to its high integration and excellent driving performance, such as automobilesOBCAir conditioning compressor, communication power supply, server power supply, outdoor energy storage power supply, etc; Isolation drive productsSLMi33xEquipped with powerful protection functions, due to negative pressure shutdown, soft shutdown, and highCMTIIt is particularly suitable for application scenarios with extremely high reliability requirements, such as automotive main inverters, high-performance servo drives, high-power frequency converters, and power gridsSVGOther application fields.
&Nbsp;
At the same time, the exhibition company also brought us a new generation of products——Isolation drive productsSiLM5992、SiLM5932、SiLM5three hundred and fiftyThe characteristics of this series of products are faster driving speed and stronger driving ability. These products are very suitable for driving based on the third generationSiC、GaNPower semiconductor devices made of materials. In addition to driving products, this exhibition also brought many new interface and signal chain products that the company has recently launched. These products also reflect the technological advantages of Suming Semiconductor, such as the company'sCANTransceivers, this series of products fully comply with industry standards, with data transmission rates that can reach8MbpsHas reached the leading level in the entire industry.
&Nbsp;
We also brought high-performance digital isolator products this timeSiLM572x、SiLM574x,CANTransceiver productsSiLM104x/105xThey can be widely used in industries, automobiles, and energy fields.
&Nbsp;
It is worth emphasizing that our semiconductor refrigeration exhibition this time（TEC）DriveSLM883xWe provide safe and reliable laser temperature control solutions for optical instruments and recently popular automotive lidar customers.
&Nbsp;
We have also brought intelligent photovoltaic system solutions this time——SiLM6one hundred and twentyProducts such as Digital Semiconductor fromtwo thousand and sixteenStarting from the year, we began to layout the intelligent photovoltaic industry, mainly focusing on the new energy industry, such as the shutdown of photovoltaic panels and optimized solutions. In this field, Suming Semiconductor has self-developed specialized chips, and based on the self-developed chips, the company has also developed a complete set of photovoltaic optimization and shutdown solutions.
&Nbsp;
02What is your company's strategic planning and layout in the new energy vehicle market?
&Nbsp;
Shuming Semiconductor Jiao Liansheng:China is the main global market for new energy vehicles, accounting for nearly all global sales50%.two thousand and twentyThe annual sales volume of new energy vehicles in China is approximatelyone hundred and twenty万辆,two thousand and twenty-oneThe annual sales volume of new energy vehicles in China is approximatelythree hundred and fiftyTen thousand vehicles. reachtwo thousand and twenty-twoAt the beginning of the year, the company predicted that this sales volume would reachfive hundredTen thousand vehicles. From the current sales data, the sales volume of new energy vehicles in China has exceeded this yearfive hundredTen thousand, expected to reach by the end of the yearsix hundred and fifty万辆.
&Nbsp;
Annual salesfive hundredTen thousand new energy vehicles were originally ordered by the market a few years agotwo thousand and twenty-five年的目标，现在看来这个目标已经提前三年实现了.这个趋势看来，中国的新能源汽车行业发展飞速，远高于预期.
&Nbsp;
数明半导体在早些年已经开始以公司最具优势的驱动类产品布局汽车市场，特别是新能源汽车市场。近两年，我们已经有多个产品系列完成了汽车级认证，在汽车主机厂和一级供应商大批量交付。在近两年整个半导体行业供应链比较紧张的情况下，为汽车芯片国产化贡献自己的一份力量.
&Nbsp;
数明半导体目前可以为主逆变器，车载充电机，热管理系统，电池管理系统等提供驱动、信号链和接口类产品，同时也在布局自动驾驶，车身控制，汽车照明等驱动和电源管理类产品.
&Nbsp;
03What are the challenges for domestic analog chips in automotive applications?
&Nbsp;
Shuming Semiconductor Jiao Liansheng:首先，汽车应用强调的是产品的可靠性，国产芯片起步晚，之前国内芯片主要以消费类以及低端工业应用为主，汽车芯片积累比较少，设计经验不足.
&Nbsp;
Secondly, the support capacity of the domestic manufacturing supply chain is insufficient, such as high pressureBCDThe maturity of the car specification process needs to be improved, mixedBCDLack of process resources. Mainstream European and American manufacturers have turned to waferstwelve寸。随着全球半导体供应链的缓解和产能释放，未来国产模拟芯片供应商将面临比较大的成本压力.
&Nbsp;
所以从芯片的设计到制造环节，我国的模拟芯片产业都还需要半导体从业者不断地创新和优化，提高自身的竞争力.
&Nbsp;
fourAs a well-known domestic analog chip enterprise, what do you think of the current development status of domestic analog chips? How should all parties work together to promote the development of domestic analog chips?
&Nbsp;
Shuming Semiconductor Jiao Liansheng:从行业的角度来说，半导体是非常热门的高新技术行业。模拟芯片设计相对来说门槛比较高，中小型的企业居多，已经形成规模的国产模拟芯片设计公司相对其他类型半导体元器件较少。资深的模拟芯片设计，制造等人才稀缺.
&Nbsp;
我个人希望能有政策导向或者行业协会引导，集中优势资源攻克创新领域，避免同质化竞争，从而促进产业发展.
&Nbsp;
fiveWhat did you gain from this Munich Electronics Exhibition?
&Nbsp;
Shuming Semiconductor Jiao Liansheng:在本次的展会中，我们看到本土半导体供应商带来了很多创新产品，聚焦于工业，汽车和新能源应用领域。可以看到，我们整个国产半导体产业其实也在做积极的转型，以适配市场的发展.
&Nbsp;
同时慕尼黑电子展也是半导体从业人员相互交流的一次盛会。通过这个展会，我们一起见证了国产半导体行业的飞速发展.
