in the light of USB Type-C Follow up development, USB Developer Forum (USB)-IF ）It means that we will cooperate with the International Electrotechnical Association (IEC) to unify the standardized charging interface, so that all devices can charge through the USB type-C up to 100W output power. At the same time, the safety mechanism is also designed for the wire part. If the connection port detects that the wire does not meet the certification specification, it will automatically switch to the minimum standard voltage power supply mode, Avoid burning and melting of wire due to inability to withstand voltage.
According to Jeff ravencraft, chairman of USB Developer Forum, it will further cooperate with the International Electrotechnical Association in the future. It is expected to use USB type-C as a new unified charging interface. Compared with the previous pass through mi As the unified charging interface of most devices, cro USB can charge large 3C devices such as laptop at the same time with up to 100W output power through USB type-C, and provide a more convenient use experience through the positive and negative connection feature.
Although the USB developer forum does not strictly require the specification certification of USB wire, it still provides an additional safety mechanism for the use of wire for charging. If the wire used by the user does not meet the high-voltage transmission specification, the system will automatically adjust to the standard voltage output power rate, only supply power with the lowest standard voltage, and even will not start the charging function, Avoid accidents caused by burning of connecting wire.
According to the current USB Developer Forum plan, USB type-C corresponds to DisplayPort HDMI , MHL, thunderbolt and other ports can also support up to 100W output power. According to the design, it will be able to correspond to image transmission and data transmission at the same time, and facilitate the charging of corresponding devices, so that the thickness of the device body can be reduced due to the simplification of the port, and the wire can more easily meet different connection requirements.
As for the current Intel Through the thunderbolt 3 interface design, the transmission bandwidth of up to 40Gbps can be realized through the USB type-C port. Jeff ravencraft said that in fact, according to the USB type-C design specification, the multi connection thread design can also correspond to a higher transmission bandwidth, but considering the current market demand for high transmission capacity is still not popular, It is considered that the current 10Gbps transmission bandwidth can meet the needs of most markets, otherwise it only makes the device cost higher.
