The 10th Anniversary of the Committee of 100 | Nanocore micro-analog chip technology innovation empowers automobile intelligence

From March 15th to 17th, the 10th China Electric Vehicles Conference of 100 Forum was held at the Diaoyutai State Guesthouse in Beijing. With the theme of "Consolidating and Expanding the Development Advantages of New Energy Vehicles" , the forum invited guests from all walks of life to focus on the trend of industrial change and explore new paths for industrial development.

The wave of electrification and intelligence is in the ascendant, profoundly reshaping the global automotive industry chain. With the first-mover advantage, my country has successfully led the electrification transformation of the global automobile industry. As automobile intelligence gradually deepens, China's automobile industry is entering the "no man's land" of innovation: On the one hand, automobile application innovation is rapidly iterating and constantly refreshing. Consumer awareness; on the other hand, chips are moving to the forefront of the industrial chain, and the trend of chip innovation driving application innovation is becoming increasingly obvious.

As a member of the Board of Directors of the Committee of 100, Wang Shengyang, the founder, chairman and CEO of Naxin Micro, was invited to attend the conference and delivered a wonderful speech on the topic of "The Evolution Trend of Analog Chips under the Wave of Automotive Intelligence" and shared with the guests. How nanocore micro-analog chip technology innovation empowers automobile intelligence.

A smarter car body

Today, automotive application innovation is changing at a dazzling pace, and behind it is inseparable from the continuously evolving automotive electronic and electrical architecture: from distributed to domain architecture to centralized architecture. As the system integration becomes higher and higher, the power density continues to increase. Improvement also puts forward new requirements for the chips in the system. Taking the body domain controller as an example, Nanocore can provide high- and low-side switch chips with multi-channel and lower on-resistance, as well as eFuse chips equipped with intelligent power distribution curve control, which can meet the requirements of the body domain controller in more intelligent nodes, Requirements for higher power density and smart power distribution.

NaXinWei’s rich product layout

On the other hand, it is aimed at a large number of scenes that require motor control such as rearview mirror adjustment, air-conditioning wings, window lifts, electric seats, electric tailgates, etc. The body domain controller integrates the functions of traditional distributed ECU actuators. The system puts forward hardware platform and functional integration requirements for the motor drive chip. At the same time, in order to match a variety of loads, the chip needs to implement diagnosis and processing for multiple load types. Protective function. Nanocore provides a diverse selection of motor driver chips. The motor driver solution integrates multi-channel drivers or power tubes, provides flexible software configuration to meet motor loads of different power levels, and supports rich diagnosis and protection mechanisms to provide body motors with Control applications provide diverse and comprehensive design options.

In addition, how to achieve multi-node, high-speed, and high-stability automotive system communication in a smaller space and a more complex electromagnetic environment is also one of the key challenges for vehicle body intelligence. The NCA1462-Q1 automotive-grade CAN SIC launched by Nanochip can achieve a transmission rate of ≥8Mbps when connecting multiple nodes in a star network. It maintains a transmission rate of ≥8Mbps with high EMC performance and Nanochip’s self-developed ringing suppression function. Good signal quality helps create a more robust in-vehicle communication system and promotes the intelligence of the car body.

More personalized car light interaction

From the "illuminating the road ahead" of halogen headlights to the "rhythmic coolness" of through-type LED lights, to the "interactive expression" of today's complex multi-pixel displays, nowadays, multi-pixel interactive headlights and smooth dynamic taillights are becoming more and more popular. Lighting systems have increasingly become a standard feature of smart cars. In addition to ensuring driving safety, car lighting systems are further endowed with the need for personalized expression. As the number of LED lamp beads continues to increase, for the LED driver behind each lamp bead, it means that more channels need to be integrated on a single chip to support higher current drive capabilities and have more Complete diagnostic protection and failure protection functions. The LED driver chip provided by Nanocore integrates up to 24 channels on a single chip, supports stronger current driving capabilities and complete circuit protection functions, allowing consumers to safely enjoy driving while using the colorful streamer to realize Full personal expression.

Development trends of automotive lighting systems

More efficient thermal management system

Different from the heat exchange method of traditional fuel vehicles based on internal combustion engines, new energy vehicles based on electric energy require a more intelligent and efficient thermal management system to coordinate and manage the temperature of batteries, engines, air conditioners and other related components and systems, while ensuring the functional safety of the vehicle. Get longer cruising range and service life. Currently, the thermal management system is transitioning from a distributed architecture to a more efficient integrated architecture. System designs that use domain controllers with large computing power to simultaneously control multiple BLDC motors are becoming popular. At the same time, for cost reduction considerations, integrated solidification algorithms are being used. The design of smart BLDC pre-driver to replace domain control MCU is gradually coming to the forefront. Nanocore's highly integrated NSUC1610 small motor driver SoC integrates ARM core MCU, 4-way half-bridge driver and LIN interface on a single chip to achieve efficient and real-time control of small motor applications and is widely used in thermal management Applications such as electronic expansion valves, AGS and electronic air outlets in the system. Nanocore's comprehensive product layout in sensors, signal chains, power management and other directions provides a one-stop solution for intelligent, safe and efficient thermal management systems.

Nanocore New Energy Vehicle Thermal Management Solution

Wang Shengyang said: "In the past year, we were fortunate to witness the milestone of China's new energy vehicle ownership exceeding 20 million vehicles. From 1 to the first 10 million vehicles, China's new energy vehicle industry took nearly 27 years, and The second 10 million vehicles took only 1 year and 5 months, and the development speed is amazing. The rapid development of China's new energy vehicle industry is inseparable from the efficient coordination of the entire industry chain and supply chain. As a local Chinese As an analog and mixed-signal chip company, we see that chip technology innovation plays an increasingly important role in the development of the new energy vehicle industry. We will use our local support advantages close to customers to accelerate collaborative innovation and provide the industry with more competitive While providing chip products, we will continue to contribute to consolidating and expanding my country’s new energy vehicle development advantages.”
