On May 30, 2023, the Ministry of Industry and Information Technology issued a new notice titledProvisional Regulations on Radio Management of Wireless Charging (Power Transmission) EquipmentThis regulation applies to wireless charging devices for mobile communication terminals, portable consumer electronics products, and electric vehicles (including motorcycles) that are produced or imported for sale and use in China. It will officially come into effect on September 1, 2024.
The fourth important point is that the operating frequency range of mobile and portable wireless charging devices is in the frequency range of 100-148.5kHz, 6765-6795kHz, 13553-13567kHz, and the rated transmission power does not exceed 80W. The relevant technical parameters such as operating frequency should meet the Technical Requirements for Wireless Charging (Power Transmission) Equipment.
As a leader in the domestic wireless charging industry, Nanxin Technology has recently launchedHigh Power Wireless Charging Solution - SC9610&SC8701. Paired with the upcoming receiver, it can achieve 80W wireless fast chargingProvide faster and more convenient charging methods for various smart terminals such as smartphones and laptops.
Product Introduction - SC9610
SC9610 is a highly integrated and efficient magnetic induction wireless power transmitter. It can support operation within a wide input voltage range of 4V to 22V, with full bridge output supporting up to 42V and 80W power output.
The SC9610 integrates a powerful 32-bit digital core, while also providing rich memory and peripherals. 64KB MTP and 8KB SRAM allow users to develop applications such as wireless power transmitters.
SC9610 integrates a 3-channel enhanced PWM output with a clock frequency of up to 192MHz. Integrated with a full bridge driver, a multi-channel ASK demodulation module, FSK modulation module, an analog-to-digital converter module, 6 timer modules, and a capture module.
SC9610 also integrates fast charging protocols, including DP/DM, USB-PD, VOOC, AFCP, and UFCS. The transmitter supports Q-factor detection, achieving high-quality foreign object detection. Using QFN44_ 5x5 packaging.
Product Introduction - SC8701
SC8701 is a synchronous 4-power transistor Buck Boost controller with an output voltage that can be higher than, equal to, or lower than the input voltage. Its ultra-high conversion efficiency can effectively improve the thermal performance of the system. SC8701 supports ultra wide input and output voltages, with input voltages ranging from 2.7V to 36V and output voltages ranging from 2V to 36V. SC8701 adopts industry-leading 10V/2A MOSFET drivers, maximizing the use of external MOSFETs for high efficiency.
SC8701 supports input current limiting, output current limiting, and over temperature protection to ensure that the chip can operate normally in various abnormal situations. The output voltage and input/output current limit of SC8701 can be dynamically adjusted through PWM signals, and the switching frequency can be adjusted from 200KHz to 600KHz. Customers can flexibly design according to system requirements. SC8701 is packaged in a 32pin QFN 4x4 package.
SC9610&SC8701 Charging Efficiency
This charging scheme, combined with the 50W high-efficiency and highly integrated wireless charging RTX SOC-SC9625 already launched by Nanxin, can easily achieve 50W wireless fast charging, with a charging efficiency of up to 90%. It is worth mentioning that this scheme, combined with the 80W receiver soon to be launched by Nanxin Technology, can easily achieve 80W wireless flash charging.
Conclusion
Recently, Nanxin has launched a high-power wireless charging solution - SC9610&SC8701, which has high integration and saves peripheral space. This charging solution, combined with the already launched 50W high-efficiency and high integration wireless charging RTX SOC - SC9625, can easily achieve 50W wireless fast charging. Paired with the upcoming 80W receiver from Nanxin, it can achieve 80W wireless flash charging, providing a faster and more convenient charging method for various smart terminals such as smartphones and laptops.
