1, the more common SoC 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.
2, the most used is Ti's chip, about 12 pieces. There are many options for launch, and we're one of them.
Wireless charger using radio wave transmission, radio wave is not only a kind of electromagnetic wave, its own can also transmit energy, and can penetrate the air, so that wireless power transmission is possible.
The first is field-coupled charging. First, there are two sets of asymmetrical electric dipoles on the phone and charging device. When they are close together, they produce a coupling phenomenon and achieve the transmission of current. The transfer efficiency is good, but there are distance restrictions, and large capacity charging stations are required. The second type is magnetic resonance charging, which is different from the above electric field. This method isElectrical energy is generated by the resonance of the same frequency magnetic field generated by the resonators at both ends.
Electromagnetic induction The most common way of wireless charging is to use the principle of electromagnetic induction to generate current through the primary and secondary coils, so as to transfer energy from the transmission end to the receiving end. This approach has been achieved by the Wireless Charging Alliance (Wireless? The Power? Consortium; WPC).
Wireless charger usage ti Wireless charging program : Connect the charger and data cable of the mobile phone standard ti wireless charging program to the wireless charger, and then put the mobile phone in the center position of the left and right of the wireless charger base, you can realize wireless charging, the indicator light will have a breathing effect, 5 seconds later, plug and play, convenient and quick.
electromagnetic induction type. The primary coil has a certain frequency ti wireless charging program alternating current, which generates a certain current in the secondary coil through electromagnetic inductionEnergy is transferred from the transmitting end to the receiving end.

Wireless charging has about three transmission methods: electromagnetic induction, radio wave, magnetic resonance. Three ways eachAmong them, radio wave type is not optimistic because of low power, high energy consumption and poor feasibility. From the perspective of the consumer market, the wireless charging products commonly mentioned generally use electromagnetic induction and magnetic resonance.
If you use vivo mobile phone, you can refer to the following information: Wireless charger usage: the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontally placed in the center position of the wireless charger base, you can achieve wireless charging, the indicator light will have a breathing effect, 5 seconds after the turn off, plug and play, convenient and quick.
Also, by using wirelessCharging technology, public mobile device charging stations will be possible. In theory, wireless charging technology is safe and harmless to the human body, the resonance principle used by wireless charging is magnetic resonance, which is transmitted only between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
