Mobile phone reverse wireless charging

    Recently, at the 2018 (Autumn) China Wireless Charging Industry Summit Forum, Maxim has demonstrated its latest development of Power Sharing technology, which can turn mobile phones into wireless charging transmitters, wear smart bracelets, etc. Equipment emergency charging. After the announcement of this technology, it received the attention of many customers present.

    Exclusive Power Sharing technology, mobile phone reverse wireless charging.Today's mobile phones with OTG function can charge other mobile phones (requires cable and HUB), and some mobile phone manufacturers also use this as a selling point. Of course, the wireless method is naturally more convenient. This type of design will be a differentiated selling point that reflects the R&D strength in the era of universal wireless charging.

    The Mickey MT5715 is also a fast-charge wireless charging chip that supports WPC's latest BPP and EPP requirements, while supporting the proprietary wireless fast charging protocol of mobile phone manufacturers. The power can reach 20W and support 20V 1A output. It is one of the few receiving chips that support high power on the market. Special design and device selection guarantees a high operating voltage in 20W mode, resulting in extremely high end-to-end (send input to receive output) system efficiency (greater than 90%), which is the first in China, even It is the first in the world and is one of the trends in wireless fast charging.

    The MMC MT5715 is programmable to control the output voltage (50mV/speed) and current (100mA/speed). Adaptive synchronous rectification controller for maximum system efficiency and stable communication under different load conditions. Unique overvoltage protection guarantees reliable operation throughout the life of the device.
