Industrial products and consumer electronics is very close contact, including unmanned aerial vehicles, set up security monitoring, electric vehicle charging piles and other equipment well into people's lives. However, circuit protection products in the industry, although only a small part of the design, but it is very important critical design, because the protective devices or protection products are usually at the entrance, for example, the input port power supply problems once the protection device, the entire the system will not be able to use timely, accurate and effective so protected design is becoming increasingly important.
 
Under the impetus of intelligent industry, the security industry will be the emergence of what's new? What are the new trends? Chip manufacturers how to deal with the opportunities and challenges coming? This issue electronic enthusiasts intelligent network Du Mr. Yao special industrial raw invites Littelfuse Application Manager to discuss issues related to intelligent power management at the industrial age.
 
Industrial products, circuit protection design to be reckoned with
 
Charging power supply or charging pile gradually spread in society and in the family, whether it is for indoor or outdoor nudity, their security must be indispensable. Maximum DC voltage up to 750VDC, a separate lightning protection module will be considered 10 / 20KA, with national standards to produce, use a variety of security products need to be able to better perform overcurrent protection. Because "For industrial products, high reliability is the eternal pursuit." Du Jingli so talked about. With the development of chip technology and the promotion of market power components, such as silicon carbide applications, supply power density increases, but more and more small volume, followed by the protection device is also facing new challenges, such as of surface-mount fuse and power TVS tube also will be increased.
 
We talked about the challenges faced by design protection device, which is that the engineers challenge? Du Jingli bluntly: how to determine an appropriate circuit protection is provided for many engineers gauge the program is a problem. Many engineers circuit protection merely placed in a location of the device, for example, there is a fuse, where there is a protective tube, but in-depth qualitative design inside is not enough. How to make the most of the R & D engineers quickly design what you want to meet the standard requirements consistent with the protection circuit, the problem is considered special forces, special forces for this company introduced the circuit protection design tools iDesign, which contains a fuse Select, TVS SPA selection and choice, very easily and quickly, greatly improve the efficiency of the circuit design.
 
Talked about efficiency, Mr. Du Yao added that: In industrial automation continues to be to improve efficiency, cost-saving key driving force, but the actual efficiency is reflected in cost savings. Mr. Du Yao Students also stressed: special forces company to customers the most powerful driving force is technology. Because the product is a security device, it is safe and reliable. High quality is always the pursuit of special forces, special forces customers choose the company's products are not the issue for subsequent use, to increase the reliability of the customer's product reduces post-renovation and maintenance cost savings are in disguise.
 
Usually see the board by the attack and damage induced lightning, electrostatic damage to the chip, Mr. Du Yao Health explains: protection is not in place of the performance of these are usually circuit protection devices not doing at the time of critical need. Because in normal or protection device to protect the product is not the action, otherwise malfunction, you need time and work does not start, or start the protection did not meet requirements of the standard, simple and reliable product designed to meet the design requirements are not simple we should not ignore these.
 
Now with the improvement of technology and chip technology, the growing popularity of the program, ideas and topology engineers used are not very different, the key is to grasp the details of the product. "Why do some brand products can be safe and reliable use for many years, while others insist that less than a year on the bad, to grasp the design of the device is very important, we often talked about" a penny stock "is the truth. "Mr. Du said of Yao students. He said: In general if we can guarantee the protection circuits are taken into detailed design, the overall customer's product quality has reached a very high demands of themselves, of course, it is easy to win the trust of the quality of those demanding customers .
 
On the future of the Chinese market, Du Jingli mentioned, for now the Chinese market demand, even at the bottom of shoddy counterfeit products will slowly disappear in the market, Chinese users more rich than ever, high-quality products the demand is increasingly urgent that China is now no shortage of high-end consumer, in the past need to go abroad to buy products can be purchased in the country, increasing the quality of local products. For electronic products also improve protection design to a new requirement, cost-effective products to win customers is the benchmark of the special products is precisely to meet this need, protection from product sales in China will be able to explain Chinese mainland customer acceptance of the special forces. Local special forces customers to choose high quality products to improve their product quality, reach the high standard safety and reliability of the design, but also to feel special forces to make electronic products social responsibility.
