Wireless charging methods include electromagnetic induction and magnetic commonVibration, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.
There are three main wireless charging schemes: electromagnetic induction, magnetic resonance and radio wave. First of all, electromagnetic induction wireless charging is the most widely used scheme at present. Its principle is similar to that of a transformer, which is generated by a coil at the sending and receiving endsMagnetic field to achieve wireless transmission of electrical energy. This way the charging efficiency is higher, but the transmission distance is relatively short, usually within a few centimeters.
Mobile phone wireless charging is achieved by using wireless charging technology, mainly in the following ways: Qi wireless charging: Qi is a wireless charging standard, many mobile phones and chargers support the standard. Wireless charging can be achieved simply by placing the phone on a charger or wireless charging dock that supports the Qi standard.
Radio waves. The principle is to convert the environmental electromagnetic wave into current and transmit the current through the circuit. This way transmission distancePerformance characteristics.

4. The wireless charging technology adopted by Huawei mobile phone is mainly based on Qi (odd) standard. The standard is an industry standard that is widely used for interoperability between wireless charging devices. By integrating the Qi wireless charging chip and coil on the Huawei phone, users can place it on a compatible wireless charger or wireless charging dock and start charging.
More common SOCs are IDT, TI, COPO, purple light, etc. Most of the internal mobile phones are currently using IDT receiving schemes. Texas Instruments TI receiver chips used more in the first two years, and now they have downplayed the field of wireless charging. The integration of this chip is high and the efficiency is high, but the cost of a single chip is high and some additional functions cannot be added.
The most used receiver is Ti's chip, about 12 pieces. There are many options for launch, and we're one of them.
The two charging case power management chips are different, AirPods Pro uses Texas Instruments BQ25116A, AirPods 3 uses NXP 610A3B. The wireless charging receiver chip adopts Broadcom 59356A2KUBG. In terms of MCU configuration, AirPods Pro adopts ST Method and halfThe conductor is STM32L476MGY6, and AirPods 3 uses STM32L496WGY6P.
Try to choose more than 10W power: with the more mature technology, more and more people pursue charging speed, buy a high-power wireless charger, the future software system upgrade can also be used. It is recommended that when purchasing wireless charging equipment, try to choose a wireless charger with a power of more than 10W.
AP45851 is a charging IC used in wireless charging and launching systems, compatible with the Qi protocol. The product is fully functional and highly integrated with allFunctional modules that provide excellent performance. The AP45851 is compatible with high power output, and the chip is compatible with the Qi fast charge protocol (5/9/12V application), which meets the latest Wireless Charging Alliance (WPC) Qi version specifications.
Wireless charging receiver is a small auxiliary device that contains a wireless charging chip. You just need to plug it into the charging port of the C8860, and it will enable the C8860 to support wireless charging. If you want the weight and thickness of the phone to not increase, then this is a good choice. To sum up, at the official factory, C8860 is not mentionedFor wireless charging function.
The price of tile corner protection varies due to a variety of factors, generally ranging from 2 yuan to more than 10 yuan. Product material: magnetic tile corner has different materials, including plastic, metal and solid wood. The cost of different materials is different, so the price will be different. Brand and quality: Well-known brands usually have higher market recognition, the quality of their products is relatively better, and the price is usually increased accordingly.
