Recently, Ou Yingyang, director of the smart fast charging product line of Shenzhen Hynetek Semiconductor Technology Co., Ltd., said in an interview with this site: "The USB-C interface has begun to gradually unify the market, and the related USB-C interface management chip has also ushered in A huge explosion in demand, disruptive functional experience and user fans have created a new round of dividends for it.”
Since its release, the USB Type-C interface has become popular in mobile phones, notebooks and other markets with its many advantages such as smaller and higher speed, double-sided symmetrical design, no matter whether it is plugged in or out, and bidirectional charging. Especially when the USB-C interface was added to notebooks, the interface ushered in a revolutionary "unification". The power interface, USB-A interface, DP interface, network port, HDMI interface and VGA interface were unified into USB-C. , more lightweight and simple.
However, in the fast charging market, the complicated categories of chargers and charging cables have brought a lot of troubles to users, and have greatly reduced users’ fast charging experience. Moreover, too many charging products have also caused a lot of problems. waste. According to estimates, if new portable smart devices such as mobile phones and tablets use USB Type-C charging interfaces, 11,000 tons of electronic waste can be reduced every year, which is conducive to energy conservation and is in line with environmental protection concepts.
In the semiconductor industry, along with the chip production process, problems such as chemical pollution and metal pollution cannot be ignored. Today, with the goal of carbon neutrality and carbon peaking, our country is strategically advocating a green, environmentally friendly, and low-carbon approach. The third generation of semiconductors has the characteristics of high temperature resistance, high voltage resistance, high frequency and high power, which can greatly improve energy conversion efficiency and help achieve the dual carbon goal.
It is reported that Shenzhen Hynetek Semiconductor Technology Co., Ltd. is a company focusing on smart energy control technology. It mainly provides high-performance digital-analog hybrid chip products for the fields of smart fast charging and digital energy. Huinengtai Semiconductor shoulders the mission of "core wisdom, core energy, and build a green future together" and is determined to become the industry's leading supplier of smart energy control technology.

At present, Hynetek mainly develops products around the two product lines of smart fast charging and green energy. Smart fast charging will be extended by the PD protocol to Buck charger, Buck-boost charger, load switch, DC-DC conversion, etc.; green energy will be oriented to ICT (communication servers), data centers, photovoltaic inverters, energy storage, etc. For industrial applications, we develop digital power control chips, high-voltage driver chips, power conversion chips and modules and other products.
The company's smart fast charging products have occupied a leading position in the domestic market and even the international market, especially eMarker products, which account for 60% of the global market share. The company's digital energy product line aims to break the monopoly of foreign brands in this field. Its products will participate in competition in the international market and complete the transformation from domestic substitution to world-class.
According to Mr. Ou, Huinengtai’s current market strategy is to continue to expand its leading position in USB PD, deepen cooperation with major customers in the USB PD field, build an ecological chain with USB Type-C as the main line on the device side, and focus on green Intelligent control of energy management develops our green energy product line.
In recent years, the company's products have had many successful application cases, among which Samsung launched a 45W gallium nitride fast charging kit, using Hynetek E-Marker chip; Lenovo's 65W original PD fast charging adapter was disassembled, and Hynetek HUSB350 protocol chip assisted Produce. Huinengtai's products that sell well overseas are mainly HUSB238, HUSB350, and HUSB311.
Among them, HUSB238 is a highly integrated USB PD powered end controller (PD sink controller) that has obtained USB-IF certification, TID3666. The rated power transmitted by HUSB238 can reach 100W. It is compatible with PD3.0 V1.3 and Type-C V1.4. It can also support BC1.2 DCP, CDP and SDP and Apple 5V2.4A charging protocol. It can be used in electronic devices with traditional barrel connectors or USB micro-B power connectors, such as IoT devices, wireless chargers, drones, smart speakers, power tools, and other devices.
