What chip is needed for wireless charging?

Reception The most used is TiChips, 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.

Wireless charging function requires wireless transmitting module and receiving module. 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, and the use of the receiving chip is also very simple (plug into the mobile phone charging port).; The wireless 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.

iPhone11 as Apple's flagship iPhone11 also supports wireless charging, but compared to domestic mobile phones, the charging rate may be slower, but other aspects are still very strong, such as iPhone11 has a variety of different colors to choose from, but also the new addition of green and purple. Very little fresh.

Wireless charging requires a chip inside the device to receive electromagnetic waves and electromagnetic fields, and the nova8 does not have thisThe 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.

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 a reverse noIt uses electromagnetic induction technology, which transmits energy by using a magnetic field generated between coils, coupling the current from the charging disc to the mobile phone battery, and the charging process is no different from that of ordinary wired chargers.

3. Wireless charging does not affect the battery. Regardless of whether you use a wireless charger or a wired charger, even if you leave your hand on a wireless charging pad for a long time, or leave it on overnight, it is impossible to exceed the manufacturer's energy limit, and you cannot discharge power outside the manufacturer's lower cut-off limit.

4, no danger to the mobile phoneUh-oh. 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.

5, wireless charging is harmless to mobile phone batteries. The current wireless charger is the use of this principle, called inductive coupling technology, this technology is through the magnetic field generated between the coils, the electrical energy of a circuit into an electromagnetic transfer to another circuit in a technology.

What are the mainstream wireless charging standards

There are three mainstream wireless charging standards: Power Matters Alliance (PMA) standard: The Power Matters Alliance standard is initiated by Duracell Powermat, which is a joint venture between P&G and Powermat, a wireless charging technology company, and has a relatively outstanding comprehensive strength. In addition, Powermat is a supporting member of the Alliance for Wireless Power (A4WP) standard.

The current mainstream wireless charging power standard is 10W, which corresponds to the 5V2A charging specification. The wireless charging power supported by Apple phones is also generally in line with this standard. Some devices may support lower power, such as 5V5A, corresponding to a 5W charge rate. In contrast, the power of wired charging is usually around 18W, and the speed of wireless charging is indeed slower.

There are four basic principles of wireless charging, respectively, electromagnetic induction charging, magnetic resonance charging, radio wave charging, electric field coupling charging, the mainstream standard on the market mainly Qi standardPMA standard, A4WP standard, iNPOFi technology and Wi-Po technology. Let's take a look at the principle of wireless charging.

WP7038, wireless charging chip with multi-protocol and efficient energy transmission

With the increasing development of wireless charging technology today, WeP innovation has launched a high-performance wireless charging chip named WP7038, which has achieved a significant breakthrough in the core functions of wireless devices. As a moreThe WP7038 not only supports the mainstream charging protocols on the market, such as USB Type-C P0 and BC2, but also has the ability to customize communication protocols to provide users with a customized wireless charging experience.
