Today to share with you the knowledge of the wireless charging chip solution, which will also explain the domestic wireless charging chip manufacturers, if you can happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>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. This kind ofThe integration of the 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.
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 all functional modules, providing excellent performance. AP45851 compatible with high power output, chip compatible with Qi fast charge protocol (5/9/12V application), in line with the latest wireless charging alliance (WPC) Qi version specifications.
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.
Huawei Mate40E is equipped with Kirin 990E5G SoC chip, 7nm EUV process technology, Huawei Da Vinci architecture, NPU large core NPU micro core computing architecture, intelligence upgrade, computing power improvement, large file processing is easy to handle, and all kinds of computing tasks are easy to handle. On the front is a 5-inch AMOLED flexible curved surfaceThe screen supports a 90Hz refresh rate. 4200mAh battery with 40W wired charging and 40W wireless charging.
However, the price of this 7-inch wireless charging A13 chip mobile phone is still very touching! According to insiders, Apple plans to bring two products at the spring event, in addition to the iPhone 9, the other is a new iPad Pro. However, as confirmed by Mac Cult s, Apple sources have told him that Apple has indefinitely extended the release of the iPhone 9 and may consider listing it directly on the official website.
2, the basic principle of wireless charging is to convert the current into a magnetic field, and the magnetic field is transmitted through the air and converted into a current to be transmitted to the intelligent terminal. When the system is working, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply the system directlyElectricity. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
3, wireless charging system mainly uses the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
1, AP45851 compatible with high power output, chip compatible with Qi fast charge protocol (5/9/12V application), in line with 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.More. Now they've downplayed the wireless charging space. 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.

1, generally seen wireless charging, the use of "current magnetic effect" and "electromagnetic induction" principle. In 1819, Danish scientist Elster observed that if there is an electric current on a wire, a magnetic field will be generated around it, which can deflect the north finger. Later generations have further found that the wire is encircled into a ring, or even wound into a coil, and the magnetic field generated will be stronger and more concentrated, which is called "current magnetism.The effect ".

5, hello, wireless charging uses the principle of electromagnetic induction, which is equipped with electromagnetic induction coils on the charging device and is also equipped with the charged deviceThe electromagnetic coil.
6, wireless charging methods include electromagnetic induction, magnetic resonance, 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.
Apple 13 series phones support wireless chargingYou can turn on wireless charging by following these steps: Make sure your Apple 13 series phone supports wireless charging. The current Apple 13 series, including the iPhone1iPhone13mini, iPhone13Pro and iPhone13ProMax, all support wireless charging. Get a compatible wireless charger. You can choose the wireless charger officially recommended by Apple, or other brands that comply with the Qi wireless charging standard.
This product has wireless charging function. The iPhone13 series mobile phones are equipped with wireless charging function, compatible with qiCertified wireless charger. The Phone13 series further optimizes the wireless charging experience by supporting MagSafe magnetic wireless charging, which can provide wireless charging rates up to 15 watts, simply by absorbing an iPhone13 series phone to a MagSafe charger or a compatible QI-certified charger.
