Datang NXP Semiconductors unveiled
2018 IC China
Dec 14 2018

From December 11 to 13, THE China International Semiconductor Expo (IC China2018) was held in Shanghai. China's first automotive semiconductor company, Datang NXP Semiconductors (DNS), made an appearance in the automotive semiconductor business of Datang Telecom, showing its independent research and development and innovative new energy vehicle semiconductor products. This is also the fourth consecutive year that DNS appeared in IC China.


With the development of automobile automation, network connection and intelligence, chip plays an increasingly important role in automobile. In addition to the popular multimedia entertainment systems, intelligent key and automatic parking system, the chip is widely used in automobile engine and transmission control system, air bags, driving assistance systems, electric power steering, ABS (ESP), electronic stability system, pedestrian protection, tire pressure control as China's first auto semiconductor company, DNS was founded four years, Always holding high the banner of "based on independent research and development", racing against time and keeping up with customer needs, we are committed to creating "China Core" automobile. In this IC China exhibition, DNS respectively demonstrated the headlamp regulator chip applied to the horizontal adjustment of automobile headlights and the battery management monitoring chip for the battery management system of new energy vehicles. Electric Windows, light control, air conditioning and seat adjustment are the nerves of the car. However, China's automotive semiconductor industry has been dependent on imports because of late start and technology accumulation.

As the first automotive semiconductor company in China, DNS has been holding high the banner of "based on independent research and development" for more than four years, racing against time to keep up with customer demand, and is committed to building "China Core" automobile. In this IC China exhibition, DNS respectively demonstrated the headlamp regulator chip applied to the horizontal adjustment of automobile headlights and the battery management monitoring chip for the battery management system of new energy vehicles.


The headlight regulator chip is used to control the horizontal adjustment of the headlight beam of passenger vehicles. With low positioning, low input current, thermal overload protection and other advantages, the current market share is the world's leading.


The battery management monitoring chip is the industry's first single-core monitoring chip based on electrochemical impedance spectrum technology for lithium ion batteries, which innovatively integrates voltage, impedance and temperature monitoring functions, realizing the perfect combination of electronic technology and electrochemical technology. As is known to all, the current estimation of battery charge state is mainly achieved by monitoring the current of the battery by monitoring the chip, carrying out the charge integral calculation, with the open circuit voltage of the battery itself, and the relevant temperature compensation. For temperature compensation of high precision requirements, DNS monitoring battery management chip based on electrochemical impedance spectrum measurement technique, no external thermocouple sensor for battery internal temperature information, the cost savings at the same time, this scheme can reflect internal temperature of the batteries, as computing SOC battery management system to provide more accurate data to support.


In addition to focusing on the field of new energy vehicles and focusing on independent research and development, DNS has also made great efforts to improve quality control and process establishment. It has passed ISO 9000 system certification and launched the first ISO 26262 functional safety development process certification project in China's automotive semiconductor industry at the end of October 2015. In addition, the company has strengthened industrial coordination, established strategic partnership with universities and upstream and downstream manufacturers in the industry, and paid attention to the introduction and training of talents, laying a foundation for the company's sustainable and steady development.
