What are the wireless charging receiver chips and how to choose?

The receiving chip is divided into a solidified SOC and a microcontroller.

The more common SoCs are IDT, TI, Copo, Unicomb, etc., and most of the mobile phones currently use IDT receiving schemes. Texas Instruments TI's receiver chips were used more in the first two years, and now they have diluted the field of wireless charging. This kind of chip has a high degree of integration and high efficiency, but the cost of a single chip is high and some additional functions cannot be added.

Another microcontroller receiver chip scheme is now more popular, such as XS016 scheme, other SOP-8, etc., because of the low cost, additional functions can be added, such as adding temperature control function, etc., with strong flexibility, and the adaptation compatibility for the transmitter is also better than that of SoC.

Wireless charging reception application in TWS earphone charging case:

At present, the mainstream wireless charging and receiving chip manufacturers mainly include: IDT, TI, ST, ADI, Qualcomm, Broadcom, Lingtong, etc.

The main supplier of Samsung mobile phones is IDT, and S9 uses P9320S; The main leader of the iPhone should be Broadcom.

All of the above are in line with WPC QI standards.

If you just need to be compatible with Qi standards, domestic or Taiwanese manufacturers can also choose, cost-effective, better support, such as JL365, SOT23-6 package, cost-effective, technical support in place. It is suitable for products with wireless charging function such as Bluetooth headsets, electric toothbrushes, electronic watches, bracelets, handheld beauty devices, etc.

There is no hard link, no need to unplug the plug line, pick it up when you want to, and put it down when you want to put it down.

Circuit (it needs a vibrating circuit of an H-bridge, and an H-bridge is composed of 4 MOS tubes + oscillation capacitors + coils, well done + two drivers).
