6, among them, Shanghai Fudan Micro Company is the only WPC approved Associate-Inc level MCSP in China, while most of the other MCSPS are Regular or Adopter level. As a kind of security chip, the authentication chip is used to ensure the Internet of ThingsSex.
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.
WPC chip refers to the Wireless Power Consortium (Wireless Power Consortium)The chip used in the wireless charging standard launched. 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.
1. In theory,Wireless charging 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.
2, the principle is through the use of the magnetic field generated between the coils, generate current, for transmission.
3, open the phone, click to enter the phone Settings. On your phone's Settings page, tap the Battery and Performance TAB. In this page, click Battery in the right column to enter the battery page. Click to enable the wireless charging function. pointHit the bottom corner know, turn on the wireless charging function.
4, mobile phone wireless charging system mainly adopts the principle of electromagnetic induction, energy coupling through the coil to achieve energy transfer. When the system works, 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 power to the system directly. Wireless charging technology is a special way of power supply, it does not need the power line, rely on electromagnetic wave propagation, and then the electromagnetic wave energy into electricity, and finally achieve wireless charging.
5, buy a wireless charger: Choose a wireless charger that matches your phone model and brand.It should be noted that the charger should comply with the Qi standard, which is a widely used wireless charging technology. Plug the wireless charger: Plug the wireless charger into a power outlet, and then plug the charger's power adapter into the charger. Prepare the phone: Find the wireless charger compatible location on the back of the phone.
AP45The 851 is compatible with high power output, and the chip is compatible with the Qi fast charge protocol (5/9/12V application), which meets 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.
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 and receiving end, and the sending end coil is connected to the cable powerThe source generates an electromagnetic signal, and the receiving coil senses the electromagnetic signal at the transmitting end to generate a current to charge the battery.
The wireless charger uses the electromagnetic wave induction principle to charge, similar to the working principle of 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. Electromagnetic induction charging This is currently the most widely used scheme, the circuit structure is relatively simple, the cost is low, but the transmission distance is short, affected by the location.
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.
The most used receiver is Ti's chip, about 12 pieces. There are many options for launching,We are one of them.
CPS focuses on the field of wireless charging, providing high-performance wireless charging IC solutions, its product CPS4021 is an integrated wireless charging receive/transmit function SoC chip, suitable for a variety of devices, including mobile phones, tablets, smart watches, mobile power supplies and power tools.
