1, the wireless charger can not be charged without the wireless charging receiver chip. To achieve wireless charging of products such as mobile phones, there must be two parts: the transmitter, which is connected to the power supply and is responsible for transmitting electrical energy into a wide space; Receiver, oneGenerally installed on electronic products to receive electrical energy.
2, this helps remove dust, dirt or oxides that cause connection problems. Seek professional help: Contact the phone manufacturer or authorized repair center for professional help with the knowledge and skills to inspect and repair the internal components of the phone.
3, no effect, his principle is like forming a transformer, this side of the power induction. As long as the contact is stable, the charging time is reasonable, no impact. 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 cordWith the latest wireless charging technology.
4. Try to replace another wireless charging base to charge the phone and determine whether the fault is the fault of the mobile phone or the wireless charger. The non-Huawei wireless charger may be incompatible with the mobile phone, resulting in abnormal wireless charging function.
5, 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.
6, at this time should pay attention to whether there is a metal object placed on the wireless chargerh2>At present, the most used is Ti's chip, about 12 pieces. There are many options for launch, and we're one of them.
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.
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.
Huawei Mate40EEquipped 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, all kinds of computing tasks easily.
Broadcom created a lighting circuit with the BCM59350 receiver chip. This circuit is compatible with wireless charging standards such as PMA (300 kHz), A4WP (78 MHz) and Qi (200 kHz). When supporting different charging power, the 10×10mm chip is better than the wall orUSB charger charging time is short.
Mobile phones that support wireless charging: Xiaomi Huawei Mate 20 Pro, Samsung S10 Plus. Personally recommend Mi 9. The Mi 9 uses a Snapdragon 855 processor and a 39-inch Samsung OLED water drop screen, which accounts for 90.7% of the screen.
