1, the most used is Ti's chip, about 12. There are many options for launch, and we're one of them.
2, wireless charging PCB, different functions, the required components are different. The required components are: resistor, capacitor, resonant capacitor, resonant coil, MOS tube, control chip, protocol chip.
3, Millet 10 new flagship Mi 10, has up to 30W wireless flash charge function, minutes to increase the power, and there is 10W fast wireless backcharge, that is, you can charge millet 10 for other mobile phones that need to be charged.
4, the realization of wireless charging function requires a wireless transmitter module and receiving module, and now the new mobile phones launched by the major mobile phone brands on the market have built-in wireless charging receiving module, some mobile phones without built-in receiving module need an external receiving chip, the use of the receiving chip is also very simple (plug into the mobile phone charging port); wirelessThe charger needs to be connected to the power supply, but the phone can be placed on the wireless charger for wireless charging of the phone.
5, wireless charging requires a chip built into the device to receive electromagnetic waves and electromagnetic fields, and nova8 does not have this chip. In addition, wireless charging is not as efficient and fast as wired charging, so it may not be necessary for all users. The nova8 does not currently support wireless charging, but it does support 40W wired fast charging, which can be quickly charged in a short time. If you need wireless charging, you can choose other mobile phones that support wireless charging.
6. These phones are well received for their brand recognition and advanced technology. For example, the Mi 9 is equipped with the world's first 20W wireless flash charging technology, while the Samsung S10 series supports wireless accelerated charging and wireless shared charging technology. Huawei Mate20PRO was a leader at that time, with reverse wireless charging function. When buying a phone that supports wireless charging, there are a few things to be aware of. First, make sure the coil of the wireless charger is properly aligned with the phone.
Wireless charger charging speed is slow, there are the following possibilities: 1, wireless charger wireless charging power itself is not large. 2, the wireless charging receiver of the mobile phone, the charging current supported is not large. It is recommended to change a high-power wireless charging board, such as a certain meter, which has more than ten coils, although it is not opened at the same time, the effect will be good.
Low charging efficiency: Compared with wired charging, wireless charging is less efficient. That means it takes longer for users to fully charge. In addition, since wireless charging requires energy conversion between transmit and receive, it may be conductiveShortened battery life. Slow charging speed: Due to the low efficiency of wireless charging, the charging speed is relatively slow. This causes users to have to wait longer to complete the charge.
Low charging efficiency Since it is for mobile phone charging, the speed of charging is of course the first, even if you can do "wireless" in the application way, but for the most basic requirements of charging speed can not be reached, then the experience will probably be a discount.
First, the charging speed is slower than that of wired charging. Now mobile phones are popular fast charge, 40 or 50 watts, 50 or 60 watts of output power, basically more than half an hourIt can be charged to more than 80%, which is not comparable to wireless charging. Second, portability and versatility are worse than wired charging. Wired charging can simply take a charger, or even not take it, borrow a colleague or sweep a charging bank to meet the needs.
The charging speed is relatively slow. In the era of fast mobile phone charging, wireless charging is very slow. Now most of the wireless charging only support 5W charging, a little faster is only 5W. And wireless charging really can not meet our needs.
Because, to buy a wireless charging device price is still relatively expensive. Nothing good

4, iPhone11 as Apple's flagship iPhone11 also supports wireless charging, but relative to domestic handsFor the machine, the charging rate may be slower, but other aspects are still very strong, such as the iPhone11 has a variety of different colors to choose from, and also the new addition of green and purple, very small and fresh.
AP45851 compatible with high power output, chip compatible with Qi fast charge protocol (5/9/12V application), which conforms to the latest Wireless Charging Alliance (WPC) Qi version specifications. The AP45851 uses the unique CNS-chip as System technology to fully integrate a variety of high-performance mixed-signal functions, such as low-power device detection during standby and foreign object detection (FOD) for secure wireless charging.
Wireless charger refers to the use of electromagnetic wave induction principle for charging equipment, the principle is similar to a transformer. There is a coil in the sending end and the receiving end. The sending end coil is connected to the wired power supply to generate the electromagnetic signal, and the receiving end coil is induced to generate the electromagnetic signal at the sending endThe current charges the battery.
A receiving/transmitting coil is arranged at both ends of the mobile phone and the wireless charger. The current of the wireless charger generates a magnetic field through the coil at the transmitting end. When the coil at the receiving end of the mobile phone is close to the magnetic field, the current will be generated. Well, it's a bit of a headache to look at this principle.
The wireless charger receiving antenna is a key component in the wireless charging device, which acts like the secondary coil of a transformer and is responsible for receiving the energy from the charger and converting it into electricity that the device can use. This textThe wireless charger receiving antenna will be introduced in detail, and its role in the wireless charging system will be briefly reviewed. In the wireless charging system, the receiving antenna and the charger cooperate to complete the energy transmission.
The wireless charging system mainly uses the electromagnetic induction principle, and the energy is transmitted through the coil continuous energy coupling. When the system is operating, the input end converts the communication mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After the wireless charger coil passes through the power supply module, the output direct current is converted into high frequency communication power supply through the 2M active crystal inverter.
