via:充电头网     time:2018/12/7 0:41:44     readed:137

Through the disassembly of dozens of popular wireless charging devices on the market, it is found that more and more products adopt high integration schemes, which are simple and convenient for rapid production.DevelopmentProduction and marketing.

I. Solution of Wireless SoC Chip Charging

The wireless charging transmitter chip is basically composed of three chips, namely driver chip, MOS chip and main control chip. Under the MCU scheme, the control chips, driver chips and operational amplifiers are all independent, and there are quite a lot of peripheral components. In a word, they are very complex and have too many components. There are many kinds of materials, and the production and testing process is complex, which is not conducive to the rapid development, production and marketing of products.

SoC, or System on a chip, refers to the integration of a complete system on a single chip. At present, the relatively common definition of SOC scheme is: SoC is the integration of master control and driver. But there are also voices that say this is not accurate, master, driver, MOS integration is the real SoC. The SoC mentioned below, for the time being, is based on the first statement.

Second, MCU master control PowerStage intelligent power full bridge scheme

At the same time, there is a class of schemes in the market, which are different from the SoC, mentioned above but also highly integrated: the MCU master PowerStage intelligent power full-bridge scheme. Different from SoC, the PowerStage smart power full bridge of this kind of scheme integrates the driver and MOS into one, and the advantages of the two are different. For this scheme, we can understand it as a transition from MCU to full integration SoC.

III. Qi Certification Wireless Charging Mobile Phone
