2022-12-10 Views：33
The breakthrough in charging power of the new Apple iPhone 13 Pro Max is bound to have a significant impact on the development of the entire fast charging accessories market, and 30W PD fast charging accessories are also expected to enter a golden period of development with the advantage of iPhone 13 series phone shipments, and 30W fast charging industry chain related companies will also usher in new market opportunities.
Among them, the USB PD protocol chip as a key component to identify the fast charging function, in the fast charging accessories iteration process becomes more important.
Fast charging protocol chip according to the different application scenarios, can be divided into charging side (DFP), receiving side (UFP), dual role end (DRP) three types.
Among them, DFP chips are mainly used for fast charging chargers, car chargers, USB plug-in boards and other scenarios; UFP chips are mainly used for wireless charging input identification, power tools and some USB-C to other interface adapter cables, etc.; DRP chips have bi-directional identification function, the most typical applications for mobile power, outdoor power, laptops and tablet PCs that support PD fast charging.
In the field of fast charging source accessories, chargers, car chargers, mobile power market is most affected by the iPhone 13 series, so the DFP and DRP two fast charging protocol chip becomes more important.
According to BON incomplete statistics, there are 36 original chip manufacturers such as Infineon, Huinengtai, Tiande Yu, Yingjixin, Zhirong, Nanxin, Ruixin Micro, Meishi Semiconductor, Yunsilicon, Qinheng Micro, Weike, etc. have launched 152 DFP protocol chips that can be used for USB PD fast charging chargers.
At the same time, these DFP protocol chips can also be divided into various types according to the degree of integration, such as Infineon, Intel Core, Wei Hao and other manufacturers launched a single-chip dual C-port protocol chip; Zhirong, Intel Core and other manufacturers launched a protocol chip with an integrated buck controller; Yun Si Semiconductor, MES Semiconductor, Lixis Technology launched a protocol chip with a built-in synchronous rectifier controller; and in addition, there are also protocol chips with "A core of dual-charging" function, support for multi-port interconnection communication can PD fast charging protocol chip.
More noteworthy is that the world-renowned power chip brand PI, also launched the industry's first integrated AC-DC controller, primary power devices and PD protocol chip InnoSwitch-PD series, once again overturned the industry's knowledge of PD protocol chip, while also enriching the selection of fast charging protocol chip.
DRP fast charging protocol chip in mobile power, display, docking station and other areas of application more, the current market mainstream DRP chip suppliers are mainly 17, launched a total of 39 controller.
BON disassembly data analysis found that the current mobile power market is very widely used in the DRP protocol chip mainly from the core of the sea, Infineon, Tiande Yu, Ledui, Lizhi, South Core, Silan Micro, UFP and several other suppliers.
Finally, look at the UFP protocol chip part. Limited by the application of the chip scene, the number of UFP chips is relatively small, the statistics show that a total of seven manufacturers have launched 11 chips, they are DIODES, Speed Micro, Huinengtai, Infineon, Yingji Core, Ledui, Qinheng micro.
With the further popularization of USB PD fast charging technology, wireless chargers, power tools and other products to upgrade PD fast charging need to use UFP protocol chip, which has also become a market with great potential.
