Wireless charging chip (wireless charging chip qfn21pin can be used as a mobile phone)

Mobile phone wireless charging full analysis, one article to solve the mobile phone wireless charging related knowledge

Theoretically, wirelessCharging technology is safe and harmless to the human body, the resonance principle used by wireless charging is magnetic field resonance, which is only transmitted between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.

The principle is to use the magnetic field generated between the coils to generate a current for transmission.

Step 1: Buy a wireless charger First, you need to buy a wireless charger. There are many kinds of wireless chargers, and you can choose your own charger according to your needs. Step 2: Connect the wireless charger for wireless chargingReady. The main working principle of WPC chip is electromagnetic induction charging.

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 multifunctional chip, the WP7038 not only supports 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.

The popularity and application of wireless charging technologyThe characteristics of convenience and environmental protection have gradually become the new trend of mobile phone charging. Through the principle of electromagnetic induction, such as the Qi standard and the PMA standard, the phone can automatically receive energy without physical contact with the charging line.

The most used receiver is Ti's chip, about 12 pieces. There are many options for launch, and we're one of them.

What are the wireless charging receiver chips and how to choose?

1, the more common SoC are IDT, TI, COPO, purple light and so onAt present, most of the internal mobile phones are 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.

2, the most used is Ti's chip, about 12 pieces. There are many options for launch, and we're one of them.

3, try to choose more than 10W power: with the more mature technology, more and more people pursue charging speed, buy a high-power wireless charger, the future softSystem upgrades 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.

What is the role of the chip connected to the receiving end of the wireless charging coil? What is not connected to the output?

1, 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, for secure wirelessCharging Foreign body detection (FOD). The high level of integration and advanced features help simplify the system design of application engineers, and the periphery is extremely simple, while greatly reducing the difficulty of PCB design.

2, 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 an electromagnetic signal, and the receiving end coil senses the electromagnetic signal of the sending end to generate a current to charge the battery.

3, the mobile phone and wireless charger are arranged at both ends of the receiving/transmitting coil, wirelessThe charger current 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, and then it will be converted into usable DC current by the rectifier and voltage regulator filter circuit built in the mobile phone. Well, it's a bit of a headache to look at this principle.

4, when the receiving end is placed in the charging area of the transmitting end, the transmitting end will generate an alternating magnetic field, which causes an induced current in the receiving coil at the receiving end. This current will charge the battery through the charging circuit, thus achieving the function of wireless charging. It should be noted that although wireless charging technology is convenient and easy to use, there are some limitations and challengesFight.

5, the use of electromagnetic induction principle for charging equipment, the principle is similar to the transformer, through the transmitter and receiver end set coils, the transmitter coil under the action of power to send electromagnetic signals, the receiving end coil to receive electromagnetic signals and electromagnetic signals into current, so as to achieve the purpose of wireless charging.
