This article gives you a talk about wireless charging mobile power protocol chip, as well as wireless charging mobile power program corresponding knowledge points, I hope to help you, do not forget to collect the site oh. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, Please ask noneLine charging receiver chip what, how to choose?
Domestic enterprises do not have many wireless charging chips, let alone the mainstream, becauseMost of the wireless charging chips produced are purchased from abroad.
Broadcom created a lighting circuit with the BCM59350 receiver chip. This circuit is compatible with wireless charging standards such as PMA (300 kHz), A4WP (78 MHz) and Qi (200 kHz). When supporting different charging powers, the 10×10mm chip has a shorter charging time than a wall or USB charger. The Broadcom charging device also has a built-in magnet to correct the position of the induction coil.
In developing a truly wireless future, EnerOne of the biggest names is gyous, which debuted its WattUp wireless charging technology last year. Now, it is working to make this technology more accessible thanks to the launch of its new DA2223 receiver chip, which is designed for small electronic devices such as smartphones. The chip itself measures 7x4x0.5 mm, making it a fraction of the size of a coin.
AP45851 is a charging IC used in wireless charging and launching systems, compatible with the Qi protocol. The product is fully functional and highly integrated with all functional modules, providing excellent performanceTo be more dirty, but this version of the charging treasure color is too single, there is not too much choice. However, the youth version of Xiaomi wireless charging treasure has black and white, which are still more classic colors. The shell material is different, the standard version of Xiaomi wireless charging treasure is metal, and the youth version of Xiaomi wireless charging treasure is plastic. The weight is different.
Compared with the Xiaomi wireless charging treasure 10000mAh on sale, the overall appearance of this Xiaomi wireless charging treasure youth version has not changed much, but it has been changed to a plastic shell, the color has been increased to black and white two options, the capacity is also 10000mAh, but the body weight is about light75g, the overall thickness is about 8mm thinner, more convenient to carry.
The packaging is almost the same as the old model except for the name. Product specifications are listed on the back.
Compared to the 149 standard version, the youth version is about 70g lighter. Support while charging, can be used as a wireless charger. Cons: USB-C can only be used for input, not output. Plastic case, feel less than the standard version.
AP45851 compatible with high power output, chip compatible with Qi fast charge protocol (5/9/12V application), in line with 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.
Plays the role of metal isolation to prevent energy waste,Improve charging efficiency.
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.
Wireless charging technology is the use of electromagnetic induction principle, in the sending and receiving end with the corresponding coil to send and receive the induced current to charge.
1. The fast charging protocol of the charging bank includes Huawei SCP fast charging protocol and Qualcomm QC protocol. Huawei SCP Fast Charge Protocol The full name of Huawei SCP Fast Charge Protocol is Super Charge Protocol, and the full name of FCP Fast charge protocol is Fast Charge protocol. In the early days, Huawei used the FCP fast charge protocol, which had the characteristics of high voltage and low current, such as the 18W of the early 9V2A.
2. The fast charge protocol of the charging bank includes Huawei's SCP fast charge protocol and Qualcomm's QC protocol. Huawei SCP fast chargeProtocol The full name of Huawei SCP Fast Charge protocol is Super Charge Protocol. The full name of the FCP Fast Charge Protocol it used before is Fast Charge Protocol, which features high voltage and low current, such as the early 9V2A 18W charging. The full name of Qualcomm's QC agreement is Quick Charge.
3. There are 10 kinds of fast charging protocols. Fast charging protocols include PD protocol, QC protocol, AFC protocol, PE protocol, Huawei FCP and SCP protocol, VOOCThe next 10 types of flash charge protocol, FlashCharge protocol, ChargeTurbo protocol, Private Fast Charge protocol, fast charge protocol. Different fast charge protocols are applicable to different brands of mobile phones. When purchasing a charging bank, you need to choose a charging bank that supports the corresponding fast charge protocol according to your mobile phone brand.
4, there are mainly the following fast charging protocols: Qualcomm Quick Charge protocol, USB Power Delivery (USB-PD) protocol, Mediatek Pump Express Plus protocol. Qualcomm QThe uick Charge protocol is a fast charge protocol introduced by Qualcomm, which realizes fast charging by increasing charging voltage and current.
