1, as shown in the figure above XSP01 this PD by the electrical end (or decoy) chip used in the circuit, can support PD QC fast charge, chip cancelled, can support QC fast charge, no impact on the original wireless charging scheme circuit, this is unique, convenient and flexible use. 2, reliability: the digital technology used to improve the stability of the chip, so that it is not easy to be affected by the external environment, for the stable operation of the equipmentGuarantee. 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.
3, the working principle of 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.
4, in design, XSP08 has intelligence,When the product requires 12V but the charger provides a maximum of 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.
5, the internal protocol chip, so in order to let the charger output fast charging voltage, such as 5V/9V/12V/15V/20V, you need to add an XSP06 power chip on the productThe wireless charging of the piece is also bound to follow the trend of increasing the PD fast charging protocol.
2, Yes. Apple wireless charging protocol is qiPD wireless charging scheme , 12 series of wired charging support pdPD wireless charging scheme , but to buy a c port charger, Apple from iPhone8 wireless charging, Has only expanded the open 5W battery charging output power, compared with other mobile phones in the same industry, this output power is not high, belongs to an ordinary output power level.
1, wireless charging PD wireless charging scheme PD wireless charging scheme , wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging PD wireless charging scheme , when the current of the power supply through the coil (wireless charger transmission coil) will generate a magnetic field, other unenergized coils (mobile phone end of the coil) close to the magnetic field will generate current, charging for the mobile phone.
2, wireless charging principle: electromagnetic induction. Charging base toWhen the two are close, the generating coil generates a certain current in the receiving coil of the mobile phone based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then begins to supply power to the mobile phone from the charging seat. Magnetic resonance.
3, the main principle of wireless charging is the electromagnetic induction principle. It is charged in a non-contact manner, transferring electrical energy by generating a magnetic field between the charger and the device being charged. The following explains the principle of wireless charging in detail. Wireless charging technology is mainly based on the principle of electromagnetic induction. Specifically, AC magnetism is generated on the chargerIn the field, the electric energy is transferred to the device through the action of the magnetic field, and the wireless power supply is realized.
