Shanghai Nanxin Semiconductor Technology Co., Ltd.: Using “chips” to manage “electricity”

Shanghai Nanxin Semiconductor Technology Co., Ltd. was established in Zhangjiang Hi-Tech Park, Pudong, Shanghai at the end of 2015. It focuses on power management related to lithium batteries, charge pump/DCDC/ACDC power conversion, wired/wireless fast charging protocols, lithium battery protection and other power management fields. Nanxin's startup team came from Texas Instruments and all have more than 10 years of industry work experience. They have been deeply involved in the power field and have worked together for many years. With the rapid development of the company, Nanxin continues to introduce outstanding talents in the industry, build a top R&D team, and adhere to the product culture of continuous innovation, committed to providing the industry with complete IC system solutions with high performance, high quality and high economic benefits.

At present, Nanxin's IC products have been frequently used in products of well-known domestic and foreign brands such as Xiaomi, OPPO, Lenovo, Samsung, DJI, and BBK due to their excellent performance; since 2019, several products powered by Nanxin IC have been successfully introduced into the Apple Store. With Nanxin's continued focus on these areas in the future, Nanxin's products will be widely used in various products and industrial products such as charging peripherals, smart phones, PADs, notebooks, TVs, drones, smart homes, etc.

Leading the way in domestically produced power management chips

Shanghai Nanxin focuses on the fields of buck-boost, chargers and power management products. In the market of accessories such as adapters, it has led the domestic substitution together with other excellent domestic manufacturers. In the field of mobile phone chargers, especially the latest third-generation high-power charge pump charging products, it has taken the lead in breaking the foreign monopoly. It is currently the only domestic manufacturer that has achieved controllable power management in mass-produced charge pumps for branded mobile phones. This product is technically difficult, has high performance requirements, and needs to undergo various rigorous tests by mobile phone manufacturers, which fully reflects Shanghai Nanxin's R&D and technical capabilities, and is also the reason why Shanghai Nanxin applied for the "Technology Breakthrough Award".

In addition, Nanxin has launched a variety of mobile power chip solutions, including SOC and charging management chips used with MCU, DCDC power chips, etc. Various solutions always adhere to the principle of safety first, providing customers with all-round safety protection. Supporting from 1 lithium battery to 4 lithium batteries, from fixed 5V input and output to supporting various protocols, helping customers quickly realize product design and quickly bring it to market.

40V car power chip comes out

This year, Shanghai Nanxin has achieved a leap forward in the field of high-power charge pump charging for mobile phones. In the future, it will continue to deepen its presence and consolidate this market, accumulate experience and smooth the process in this automotive-grade product project, laying a solid foundation for its subsequent large-scale entry into the automotive electronics market.

Nanxin has a variety of on-board power chips that can be used for 40V on-board charging, including synchronous buck-type DCDC and synchronous buck-boost DCDC, which efficiently support a wide range of outputs from 3.3V to 20V. At the same time, Nanxin has launched a variety of on-board charger reference designs with various fast charging protocol chips, supporting various fast charging protocols, including USB PD protocol, to help users quickly implement on-board charger designs of different specifications.

SC8551

The leader in mobile phone power management

At present, Shanghai Nanxin has strongly entered the high-end consumer market of mobile phones. For example, SC8551 is the only charge pump charger currently in mass production for brand mobile phone customers. SC8551 is the first charge pump charger officially launched by Chinese power supply manufacturers, and it is also the only manufacturer that has officially mass-produced charge pump chargers. This product has gone through strict certification processes such as single-board testing, whole machine testing, and small-batch trial production by brand customers, and was officially introduced into mass production in September this year, with good market feedback. This product was the first to break the foreign monopoly, passed certification in a short period of time and officially entered mass production, which once again demonstrated Nanxin's strong R&D capabilities and market acumen, and quickly gained the favor of various brand manufacturers, and launched in-depth cooperation with many brand mobile phone manufacturers, and seriously threatened the dominant position of a number of international manufacturers in the market.

I believe that in the near future, with the joint efforts of excellent domestic manufacturers represented by Shanghai Hainan Xin, comprehensive domestic substitution in the field of mobile phone fast charging will soon be achieved.

Company development history and prospects

Nanxin has R&D centers and offices in Shanghai, Chengdu, Shenzhen and Taipei. The team size has expanded rapidly and attracted many very experienced and outstanding talents to join.
