1, if it is a simple wireless charging base there is no storage function wireless charging board accessories , it is equivalent to our commonly used mobile phone charger, but it is wireless charging, the phone can start charging on it. Wireless chargers generally have 5W and 10W fast charge.
2, Millet wireless charger can store electricity, millet wireless charger can not store electricity, because it is not with the charging treasureThe same, it just turns the previous wired charging into wireless charging board accessories wireless charging, we do not need to find a data cable inserted into the charging interface of the phone to achieve charging, it is necessary to use the charging head to connect to the power supply to use, can not store electricity as a charging treasure.
3, wireless charger needs to be connected to the power, if you want to do not connect the power of wireless charging, you can choose a wireless charging treasure, search YMP wireless charging treasure can find a lot, a wireless charging treasure in the bag, no longer need to take the charging line when you go out, as long as the phonePut together with the wireless charging bank, the phone is automatically charged, which is very convenient to use.
4, mobile power is a battery, wireless charging is a charger, mobile power with any time to use.
5, first of all, there is no virtual charge of the wireless charger, you said that this situation should be the wireless charger charging cut-off voltage is not accurate, lower than the normal 5V standard voltage, so look at the battery has been fully charged, the actual is not full, there is another situation is the wireless charger in the entry of small current charging, At this time, looking at the charging indicator light has changed color to show full, realResistor, capacitor, resonant capacitor, resonant coil, MOS tube, control chip, protocol chip.
Control chip: manages the entire wireless charging process, including voltage regulation, power control, communication and other functions. Power amplifier (PA) : Increases signal strength in order to transmit energy efficiently. Oscillators and modulators: Generate high-frequency AC signals for wireless transmission. Coils: Used to generate or receive electromagnetic fields, are a key part of wireless charging.
The transmitting end is the wireless charger, and the receiving end is the mobile phone. There is a coil at the transmitting end and a coil at the receiving end. hairThe shooting end transmits energy through the control board and coil, and the receiving end receives energy through the control board and coil, so that wireless charging can be achieved. The following picture shows the charging situation of Samsung S6 mobile phone and Polopai Technology's wireless charging mobile power supply. The mobile phone can start charging when it is placed on the wireless charger, without charging through the USB interface connection.
Single-layer board: that is, only one side of the board is coated with copper and the other side is not coated with copper. Usually the components are placed on the side without copper, and the side with copper is mainly used for wiring and welding. (2) Double-layer board: that is, two surfaces are coated with copper circuit boards, usually called one side of the Top (Top Layer and Bottom Layer. Generally, the top layer is used as the component surface, and the bottom layer is used as the component welding surface.
The useless end of k.MCU should be connected to the high, or grounded, or defined as the output end, and the integrated circuit should be connected to the power supply and ground end, do not hang. l. The input end of the idle gate circuit should not be suspended. The positive input end of the idle op amp should be grounded, and the negative input end should be connected to the output end. m. Printed boards try to use 45 line wiring instead of 90 line wiring to reduce the external transmission and coupling of high-frequency signals.
Board,A printed circuit board is a baseboard for electronic devices that includes metal wiring, holes, and other specific functions to connect electronic components. PCB is mainly used as a circuit board support, connecting various electronic devices, and providing the power supply, signal transmission and data processing functions of the circuit board. The motherboard, also known as the mother board, host board or system board, is the central circuit board inside the computer and is one of the most important components in the computer system.
As shown in the figure above, XSP01 is the receiving end of PD(or deceive) when the chip is used in the circuit wireless charging board accessories , it can support PD QC fast charging, and after the chip is cancelled, it can support QC fast charging, which has no impact on the wireless charging scheme circuit of the original wireless charging board accessories , which is unique. Convenient and flexible use.
Reliability Wireless charging board accessories : The digital technology used improves the stability of the chip, so that it is not easily affected by the external environment, and provides protection for the stable operation of the equipment. Flexibility: According to user needs, the chip can adjust the output voltage and current, which can not only charge fast when the battery is low, but also extend the battery life, and realize the personalized charging strategy.
The working principle of the PD decoy chip can be likened to an intelligent "communication master". Designed to mimic the interface of a specific power management unit, it interacts with the charger through a built-in communication module, just as a host at a dinner party guides guests through precise signal transmission, allowing the charger to recognize and provide the voltage and current required by the device.
By design, the XSP08 is intelligent when the product needs 12V But when the charger provides a maximum 9V (such as the iPhone 20W charger), it can automatically downshift to 9V without user intervention. In addition, the chip has a variety of built-in fast charge protocols, such as PD0/0, Huawei FCP/SCP, QC0/0 and Samsung AFC, which can automatically identify and use the protocol connected to the charger for efficient communication, improving the use experience.
