The AP45851 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 connectedThe wired power supply generates electromagnetic signals, and the receiving coil senses the electromagnetic signals at the transmitting end to generate current to charge the battery.
Play the role of metal isolation, prevent energy waste, improve charging efficiency.
You have normal no-load voltage and low on-load voltage. The no-load voltage is normal, indicating that your wireless charging transceiver circuit is normal, but the voltage is pulled down after the load, the most likely is that your coil matching is not good, resulting in insufficient power received by the output end, so the charging voltage will be pulled down.
The principle is very similar to that of a real radio. That is, the sending endHigh-frequency alternating magnetic field is sent, and the receiving end changes energy through LC resonance. Here's a picture for you. In the second half of this year, there is also a period of homemade wireless charging equipment, but the information is placed in the unit. I can't upload it.
The working principle of the wireless charger: The electromagnetic induction principle is adopted, and the energy coupling through the coil is realized. 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. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.Which ones? How do you choose?
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 chip itself measures 7x4x0.5 mm, making it a fraction of the size of a coin. The chip doesn't work alone, but according to EnergousDepending on the power level of the device it is using, the chip can be coupled to a matching circuit of two standard discrete components and a small antenna, which will become a complete wireless charging receiver.
The most used receiver is Ti's chip, about 12 pieces. There are many options for launch, and we're one of them.
