PD fast charge protocol and Type-C interface relationship

2019-10-23 17:58:54

What is the relationship between the PD Fast Charge Protocol and the Type-C interface?  After the fast charging technology has gradually become popular, many people have already learned about fast charging technology.  As a Chinese manufacturer specializing in the production of usb cables and usb power charger adapter, Sinodec Industrial Co. Ltd. can provide one-stop shopping service for customers.  But now there are a variety of fast-charge agreements on the market that make it impossible to choose. Today, follow Sinodec Industrial Co., ltd. to find out what the USB PD fast charge protocol is and the relationship with the Type-C interface.  Mobile phone, PD charging head, Type-C data cable

First, USB Type-C interface The USB Type-C port is not only more space-saving, but also has many advantages that the traditional USB-A port does not have. The most basic ones are as follows: 1. Support positive and negative random insertion; 2. When working as a USB charging cable, the Type-C port can provide up to 100W of power; 3. When working as an  USB data cables, the fastest transmission speed of Type-C port can reach 10Gbps; 4. Multi-function: Transfer files, connect monitors, connect speakers, power supply, use this USB cord, you can get all.

Connect your computer and monitor with a USB-C to USB-C  cable, powers and transmits data to the monitor at the same time, in the future, you only need one line.

Second, the PD protocol 1. The PD protocol is one of the current fast charging protocols.  It is a fast charging specification developed by the USB-IF organization.  USB PD increases power delivery through USB cables and connectors, extending cable bus power in USB applications.  The specification enables higher voltages and currents, delivers up to 100 watts of power, and is free to change the direction of power delivery. 2. The Type-C interface supports up to 5V/3A by default, but after implementing the USB PD protocol, the output power can be supported up to 100W mentioned above.

Third, mobile phone use precautions   Android P has set the PD as the charging standard that Android phones must support. In addition, Apple will also be equipped with a PD charger as standard, and PD will be fully charged or become a future standard.  When using the Apple mobile phone to delete data, you need to use the recovery tool to scan when you need to retrieve the data.

Fourth, PD charging head considerations 1. The multi-port charging head is absolutely not needed, it will cause internal interference. It seems that the area is very suitable, but it is very unsafe. 2. There is no special long line between the two ends. There are usually chips in the inside. It may not be compatible during use: if it is light, it will not be charged, and if it is heavy, it will burn the equipment. 3. A safe and reliable full-charge fast charging solution, only one:

1. Single port output (less Bug, not easy to interfere with each other); 2. Support full-speed 18W (9V2A) PD output; 3. The maximum current does not exceed 3A; 4. No need for data lines with chips (eMarker).
