Before the application of TYPE-C fast charging interface, the common interface was microUSB. This interface has 5 pins, but only 4 are used, namely VCC, GND, D plus and D-. D plus and D- are used for For data transmission, VCC and GND realize charging. Due to the influence of the wire, it cannot transmit high current. Therefore, the MicroUSB interface cannot realize high current charging, and thus cannot realize fast charging.
The most direct understanding of TYPE-C fast charging is that there is no need to distinguish the direction of the plug when charging. In addition, careful friends may notice that Type-C has more pins, which is also TYPE-C fast charging. One of the keys to improving the charging speed.
TYPE-C fast charging supports 5V\/3A charging specifications by default on the hardware. With the support of the charging protocol, the theoretical maximum output power can reach 100W, which shows the advantages of TYPE-C fast charging over MicroUSB. USB-PD protocol The fast charging chip needs to be certified by USB-IF. In addition to PD, there are QC and PPS commonly used fast charging protocols. These three fast charging protocols are the current mainstream fast charging protocols, and they all need to pass the corresponding fast charging protocols. Charge the protocol chip to achieve.
