The MCU solution cannot meet the market demand. At present, the SoC wireless charging chip is widely viewed by the industry as the most promising solution architecture. As the trend of component price increases intensifies, SoC solutions have more advantages due to fewer components. One of the characteristics is that the cost-effectiveness of the SoC solution can reduce BOM costs.
Component prices
People in the industry all know that the delivery period of MOSFETs, capacitors, chips, and other components has been continuously extended, and they are always facing shortages and price increases. As for the reasons for this, suppliers believe that the market is not in demand and there is no effective communication channel. Another reason is that the wireless charging production process is long, and this is due to the current wireless charging equipment integration is not enough, supply stability is easily affected by factors outside the industry.
The SoC integrated chip can solve these problems well. It can allow equipment manufacturers to greatly reduce the material procurement catalog and improve the stability of supply. Under the background of rising prices, integration can be achieved, which is indeed a major selling point.
Industry may set off price war
At the MIX 2S conference held on March 27th, Lei Jun devoted a lot of space to introducing the wireless charging function and took out the Belkin Wireless Charger, which was priced at 498 yuan, and the price of 528 yuan Samsung Wireless Charger and its own product. For comparison, the same support for wireless fast charging, millet wireless charger as long as the price of 1/5, only 99 yuan! The wireless charging industry may set off another round of price wars.
We speculate that the reason why such a low price can be achieved is that a large part of this is because it uses SoC solutions. From the dismantling of the charging head net, it can be found that the Xiaomi wireless charger actually uses the SoC wireless charging scheme, which fully confirms our guess.
BOM BOM Competition
First look at the actual case, the first is the traditional PCB wireless charging board, as shown below:
Under this kind of traditional MCU scheme, the control chip, the driving chip, the operational amplifier are all independent, the external components are quite numerous too, it is very complicated in all, the component is too many. The variety of stock preparations and the complex production and test procedures are not conducive to rapid product development, production, and marketing.
Let's look at another case: SoC solution, taking Yichong's fully integrated SoC wireless charger solution “EC8000 Series†as an example, as shown below.
With this SoC solution, there is only one large chip on the PCB and two MOS transistors, which are quite concise. The SOC integrates a wireless charging drive, an H-bridge driver, an op amp, and a built-in temperature protection function. One chip realizes all functions and can effectively control costs and streamline production processes.
Let's take a closer look at the comparison between the two BOM lists:
It can be seen that the MCU mainly uses 12 components, while the SoC only requires 3, obviously the latter BOM List is much less, saving a lot of components, it is more streamlined, the overall cost is naturally more low.
The reason why it can be so streamlined is that the SoC incorporates all components and functions such as voltage and current detection, power supply voltage regulation, MOS driver, demodulation of received signals, and Q value detection. As a result, the BOM List is much less, not only the overall price and cost are lower, but also the streamlined features of the SoC make it easier for the rapid development, production, and marketing of the product, so it also saves a lot of time and effort costs.
to sum up
The development path of mobile power, from the early MCU + power supply program structure, as the market matures slowly into SoC integration. Similarly, the wireless charging industry is bound to eliminate backward MCU solutions and embark on the same SoC development path. So, this kind of scheme of SoC can adapt to the market demand more, also be the cost-effective scheme that accessory manufacturer needs more at the same time.
