The UFCS fusion fast charging protocol is China's general fast charging technology standard, and the launch of this standard breaks the problem of incompatibility of fast charging protocols between different brands of mobile phones, and greatly improves the fast charging experience of consumers' mobile phones. At the same time, due to the improvement of the versatility of the charger, the waste of resources is eliminated, and the chargers of other brands can also be used for fast charging.
At present, Huawei, Xiaomi, OPPO and vivo well-known mobile phone manufacturers have launched chargers that have obtained the UFCS fusion fast charging protocol, and the original fast charging chip factory has also launched a protocol chip that supports the UFCS fusion fast charging protocol, and has been applied in the fast charging charger and mobile power supply to provide consumers with more versatile accessories.
The charging head network learned that Yingjixin IP5385 has recently passed the UFCS certification, which is the first batch of mobile power chips in the industry that have passed the UFCS certification, certificate number: 0302347161930R0M-UFCS00078.
UFCS (Universal Fast Charging Specification) is a new generation of converged fast charging protocol led by the Academy of Information and Communications Technology, Huawei, OPPO, Vivo, and Xiaomi, and jointly completed by a number of terminals, chip companies, and industry partners. It aims to solve the problem of complex and changeable and incompatible fast charging standards on the market, and also play a positive role in promoting energy conservation and environmental protection by improving the user experience.
In order to accelerate the standardization and development of terminal fast charging technology, based on the content of the 2021 version of the UFCS technical specifications and test methods, combined with the feedback from FCA members in product development and testing, especially the problems found during the test of the first plug-in conference, the terminal fast charging technology and standards promotion committee (TC626) jointly revised and released the 2022 version of the "Technical Specification for Mobile Terminal Convergence Fast Charging" and "Test Method for Mobile Terminal Convergence Fast Charging".
The standard aims to solve the problem that different brands on the market have launched their own private protocols, resulting in incompatible charging protocols, especially between major mobile phone brands, there are many private protocols, and they are incompatible with each other, different brands use each other's chargers or mobile phone charging, and can only charge at low power, which not only causes a waste of resources, but also seriously affects the user's fast charging experience, and increases the risk and cost of upstream and downstream research and development in the industrial chain. The UFCS converged fast charging protocol has become a common fast charging standard in the fast charging industry, which can realize the unification of the fast charging market. While improving the user's charging experience, it also promotes energy conservation and environmental protection in all aspects.
The charging head network was informed that Yingjixin Technology, the original manufacturer of well-known fast charging chips in the industry, has launched the first fast-charging mobile power SOC IP5385 integrated with UFCS fusion fast charging protocol protocol, this chip integrates the fast charging protocol chip in the common mobile power supply, MCU, and synchronous buck-boost controller all in one package, supporting 2-4 strings of ternary lithium batteries and lithium iron phosphate battery applications, with MOS tubes and inductors, you can form a two-way 65W fast charging mobile power supply, so as to meet the needs of cost-effective fast charging.
Yingjixin IP5385 continues all the functions of IP5389 synchronous buck-boost SoC, the chip supports 2 USB-A port outputs at the same time, supports a two-way USB-C interface, and also supports Micro USB interface or Lightning interface input, any interface supports fast charging, supports UFCS fusion fast charging, and supports PD30 fast charging, support Huawei scp, FCP fast charging and other fast charging protocols, with very good compatibility.
The IP5385 has a built-in bidirectional synchronous buck-boost driver with an integrated charge pump that supports the use of high-performance NMOS for switching and path management. Only one chip is equipped with an inductor and synchronous switch tube, as well as a path management tube for the corresponding interface, which can form a complete 2-4 string battery and multi-interface high-power fast-charging mobile power supply. The chip supports 65W charging and discharging power, which meets the needs of mobile power supply, energy storage power supply, portable equipment and power tool applications.
The chip has built-in input over-voltage and under-voltage protection, output over-voltage, over-current and short-circuit protection, battery overcharge, over-discharge and over-current protection, supports external NTC for battery temperature protection, and built-in chip overtemperature protection. The data pins are tolerant to 30V and are ESD protected.
Yingjixin IP5385 application schematic, corresponding to each interface using VBUS switches, synchronous buck-boost circuit four switches, integrated NMOS driver inside the chip, high integration of the solution, effectively reduce BOM cost. It supports digital tube power display and four-light LED power display, and supports setting the battery capacity through resistance to achieve accurate power display.
The number of cells, battery voltage, battery capacity and maximum input and output power parameters can be set by resistors, without software development and support function customization, IP5385 SoC chip simplifies the development of mobile power supply to the greatest extent, reducing development costs and production costs.
Thanks to this highly integrated SoC chip, the demo board can be configured with five interfaces: 1C2A1L1M, which is not only compatible with classic QC, PD and other fast charging protocols, but also supports the current popular UFCS fusion fast charging, which establishes advantages for customers' products in the emerging market.
Under the active promotion of the domestic head mobile phone manufacturer Huami OV, UFCS fusion fast charging standards have been launched one after another, and ecological construction is in full swing, and some mobile phones, chargers, mobile power supplies and other products have begun to support UFCS fusion fast charging on the market, let's take a look at the actual performance of Yingjixin IP5385.
Use the Demo USB-C port based on the IP5385 SoC chip designed by Yingjixin to charge the vivo iQOO Z7, and successfully turn on UFCS fusion fast charging, with a charging power of 833v 2.92a 24.3w。
Also use the USB-C port of the demo to charge the vivo iqoo 10 pro, and successfully turn on UFCS fusion fast charging, with a charging power of 906v 3.02a 27.35w。
Finally, I charged the Reno9 5G mobile phone of another major brand, OPPO, and successfully turned on UFCS fusion fast charging, with a charging power of 89v 3a 26.87w。
The launch of Yingjixin's IP5385 synchronous buck-boost SOC has further enriched the UFCS integrated fast charging ecology and contributed to the unification of consumers' fast charging. At the same time, judging from the measured power of charging the mobile phones of the two major brands of OPPO and vivo, the power has reached about 27W, which is very good.
As a well-known domestic fast charging chip manufacturer, Yingjixin has played a leading role in adding the highly integrated synchronous buck-boost SOC chip to the UFCS fusion fast charging protocol support and successfully passed the UFCS fusion fast charging certification, bringing new solutions for high-power fast charging mobile power supply and outdoor energy storage power supply products, leading the development of the fast charging industry.
