Shulou(Shulou.com)11/24 Report--

CTOnews.com, August 7, the Ministry of Industry and Information Technology issued the interim regulations on Radio Administration of Wireless charging (Power Transmission) equipment on May 30 this year, which mentioned that "mobile and portable wireless charging equipment and rated transmission power will be increased from 50W to 80W", which will be implemented on September 1, 2024.

According to official account, SMIC recently launched its high-power wireless charging program SC9610&SC8701, which, with the launched 50W high-efficiency and highly integrated wireless charging RTX SOC-SC9625, can achieve 50W wireless fast charging, and with SMIC's upcoming receiver, it can achieve 80W wireless fast charging, and "can provide a faster and convenient charging mode for mobile phones, notebooks and other smart terminals".

SC9610SC9610 is a highly integrated and efficient magnetic induction wireless power transmitter. It can support a wide input voltage range of 4V to 22V, full-bridge output support up to 42V, support 80W power output, in addition, SC9610 also supports the latest wireless charging protocol WPC-Qi2.0 (EPP+MPP) protocol.

▲ Picture Source official account SC9610 integrates a powerful 32-bit digital core with rich memory and peripherals. 64KB MTP and 8KB SRAM allow users to develop applications such as wireless power transmitters.

SC9610 integrates 3-channel enhanced PWM output with clock rate up to 192Mhz. It integrates a full-bridge driver, a multi-channel ASK demodulation module, a FSK modulation module, an analog-to-digital converter module, six 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 to achieve high-quality foreign body detection. It is packaged with QFN44_5x5.

SC8701SC8701 is a synchronous 4-power transistor Buck-Boost controller, the output voltage can be higher, equal to or lower than the input voltage, ultra-high conversion efficiency can effectively improve the thermal performance of the system. The SC8701 supports ultra-wide input and output voltages of 2.7V to 36V and 2V to 36V. SC8701 uses industry-leading 10V / 2A MOSFET drives to maximize the use of external MOSFET for efficiency.

▲ source official account SC8701 supports input current limit, output current limit, and overtemperature protection to ensure that the chip can work properly in various abnormal conditions. The output voltage and input and output current limit of SC8701 can be dynamically adjusted by PWM signal, and the switching frequency is adjustable from 200KHz to 600KHz. Customers can flexibly design according to system requirements. The SC8701 is packaged in 32pin QFN 4x4.
