WPC chip refers to the Wireless Power Consortium (Wireless Power Consortium)The chip used in the charging standard. It can realize the wireless charging function between different brands of smart devices, which is convenient for users to wireless charge in different occasions, without the use of cables and plugs. WPC chips have been widely used in smart phones, tablets, watches, headphones and other electronic devices. The main working principle of WPC chip is electromagnetic induction charging.
The popularity and application of wireless charging technology Wireless charging with its convenient and environmental characteristics has gradually become a new trend of mobile phone charging. Through the principle of electromagnetic induction, such as the Qi standard and the PMA standard, the mobile phone without physical contact with the charging cable,Can automatically receive energy.
The most used receiver is Ti's chip, about 12 pieces. There are many options for launch, and we're one of them.
The 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.
Wireless charging PCB, different functionsThe components required are different. The required components are: resistor, capacitor, resonant capacitor, resonant coil, MOS tube, control chip, protocol chip.
Mobile phones that support wireless charging are: Millet Samsung S10 series, millet MIX2S, Nut R millet MIX2S, Huawei Mate20PRO Millet 9 mobile phone was released on February 20, 2019, in addition to Qualcomm 855 chip this product is making rapid progress in wireless charging. The Mi 9 mobile phone is equipped with the world's first 20W wireless flash charge, which is comparable to the wired fast charge.
Many models of American wireless charging chip , mainly ordinary charger 5V2A, SCP super fast charge 5V5A, FCP fast charge 9V2A, and 10V4A super flash charger. The charging head of the wireless charger can have the same, support a variety of input voltages, a variety of output power.
Need, the fast charger is divided into three models US wireless charging chip : standard 5v1AFast charge 5v2A (speed up 30%), flash charge 9v2A (speed up 50%). Wired charging and wireless charging use the same fast charging head.
The difference between wireless charging and wired charging Wireless charging and wired charging is two different charging methods, there are many differences between them, including: charging method Wireless charger first to load the mobile phone into the charging protective shell, and then the protective cover is placed on the induction base, and then the induction base is connected to the power plug, and the power plug is plugged in. Wired charging is to plug the charging cable into the charging port of the phone.
Different, wireless chargeElectrical appliances will lose when they are charged, and the loss is between 30 and 40 percent. So the ordinary charger is faster than the wireless charger. There are already fast chargers and fast wireless chargers, but the results are the same. For example, the fast charging Samsung S8 takes 90 minutes, then the fast wireless charger takes 190 minutes, which is the result of my own actual testing.
Now the wireless charging basically uses electromagnetic induction technology, the essence of electromagnetic induction wireless charging is magnetic generation, and the principle of the transformer, the sending end and the receiving end have built-in coils, when the two ends are close, the sending end coil into the high frequencyAlternating current will induce the same frequency of electromotive force at the receiving end, and then charge the receiving end after rectification and filtering. Wire communication is the use of wires to transmit electrical signals.
More common United States wireless charging chip SoC IDT United States wireless charging chip TI United States wireless charging chip , 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 plans to launch, US wireless charging chip We are one of them.
Try to choose more than 10W powerWith the more mature technology, more and more people pursue charging speed, buy a high-power wireless charger, and the future software system upgrade can also be used all the time. It is recommended that when purchasing wireless charging equipment, try to choose a wireless charger with a power of more than 10W.
AP45851 package size is small, the use of QFN24 package, strong heat dissipation, in 10W applications can also be fast heat dissipation. With its complete wireless charger performance, the AP45851 is the ideal choice for customers.
Wireless charging receiver is a small auxiliary device that contains wirelessThe charging chip. You just need to plug it into the C8860 charging port, it can make the C8860 support wireless charging. If you want the weight and thickness of the phone to not increase, then this is a good choice. In summary, at the official factory, the C8860 does not provide wireless charging function.
1, mainly to see what the role of the chip is to do US wireless charging chip , if it is only the control circuit operation drive US wireless charging chip , it must not be used, if the chip is only the control of irrelevant aspects, it may also be used for a while, anyway, the product component design has the meaning of existence, It will definitely affect the use or service life. 2, the MIT researchers said that the body's response to electric fields is strong, but the body's response to magnetic fields is almost non-, so the system will not affect human health. However, this is still a speculation, and some researchers are concerned that further tests are needed before it can be used in real life. As an electronic charging product, the charger itself can not avoid radiation, so it is inevitable that the wireless charger has radiation.
3, no harm to mobile phones. Wireless charger uses the latest wireless charging technology, by using the alternating magnetic field generated between the coils, the transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
4, generally no damage to the mobile phone. But in some special phones --For example, a mobile phone equipped with NFC/ wireless charging will affect the normal use of these functions after a magnetic ring is installed on the back cover. If the mobile phone cannot be charged properly using the wireless charging pad, it may be due to a variety of reasons. It is recommended that you try the following operations: Check whether the back center of the mobile phone is placed in the center of the wireless charging pad.
5, convenient: charging does not need to be connected with wires, as long as it is placed near the charger, there is no need to occupy multiple power sockets, there is no trouble of multiple wires winding each other. The disadvantages of wireless charging are slightly less efficient: there is also a transformer in the general charger, but wireless charging to transmit coils and receiveBecause of the limitations in the structure of the transformer composed of coils, the energy transmission efficiency is theoretically slightly lower than that of the general charger.
6, find a physical object according to the size of the shape is not good, 393=39*1000PF. (39 followed by three zeros) 391=39*10, the third digit represents the power of 10, and all electronic components are marked with this rule.
1, wireless charger is not harmful to the phone. The wireless charger uses electromagnetismInductive technology United States wireless charging chip , is to use the magnetic field generated between the coil to transmit energy United States wireless charging chip , it will current from the charging disc, coupled to the mobile phone battery, for the battery, its charging process and ordinary wired charger and there is no difference.
2, no, wireless charging will not reduce the performance of the battery faster. Battery manufacturers design the amount of energy stored in batteries to determine the amount of electricity we can use. The manufacturer sets a fixed upper cut-off voltage and lower cut-off voltage,And with electrical cycling between the two voltage ranges, as long as we choose the right voltage range, we can cycle the battery thousands of times.
3, wireless charger under normal circumstances will not harm the mobile phone, wireless charging now the working frequency is done below 1M, so the signal of the mobile phone will not have an impact.
