The USB type-c interface is a type of USB interface, specifically an interface standard (interface type). The most obvious feature of USB type-C is its support for blind insertion on both sides. With this feature, friends no longer need to worry about the wrong direction of the USB drive.

The early interfaces of smartphones were solved through micro USB and mini USB for data transmission and charging functions. The former can solve problems such as short interface life and large volume, and is also compatible with the USB 1.1/2.0 standard and OTG function at that time, so it has been used to this day. As mobile phone manufacturers increasingly demand the body, the body becomes thinner, and the requirements for transmission speed and charging speed are also increasing, it seems that micro USB is no longer the best solution.

So, we have seen an emerging interface in the mobile phone industry in the past two years - USB type-c, which has strong compatibility with micro USB and achieves unified data transmission and power supply. Low power consumption, small footprint, faster transmission and charging speeds, and powerful scalability bring you an unprecedented experience.

As the leader of the Semiconductor industry, Onsemi Semiconductor's products have always received attention from the industry among domestic hardware manufacturers. Recently, Mr. Li Wenhui, senior field application engineering manager of Onsemi Semiconductor mobile market, explained the latest USB standards and Market trend, and shared the complete scheme of USB type-c on mobile devices.

With the increasing usage of mobile devices and the lack of breakthroughs in battery technology, people's demands for charging speed have become increasingly high. Therefore, with the development of technology, USB type-c and Quick Charge (QC) technologies have become the standards for fast charging of mobile devices.

Of course, not all type-C interfaces support true fast charging standards, and for type-C interfaces that only support the USB 2.0 standard, fast charging cannot be achieved. The USB type-c solution of Onsemi Semiconductor is solved by a power controller that supports both the standard USB 3.1 interface and the USB-PD protocol and adjusts the voltage according to the power requirements of the equipment.

Onsemi Semiconductor provides a full range of flexible USB type-c scheme lineup, which not only supports high current charging, but also supports 10Ghz ultra high-speed data channel, and achieves the lowest power consumption in the industry and 95% smaller footprint than the MCU scheme in the market. In terms of data transmission, the transmission rate can reach 5Gbps or 10Gbps in USB 3.0 and Type C environments, which requires a single channel adapter driver to reduce inter symbol interference and reduce unwanted signal distortion affecting transmission, in order to comply with USB 3. x eye height and total jitter specifications.

Compared with other competing devices in the market, Onsemi Semiconductor can support the data rate of usb3.1 Gen 1 (5Gbps) and Gen 2 (10Gbps) at the same time, with eye height increased by 20% and jitter reduced by 20%. It can also be used in type-c USB 3.1 connectors that can be plugged back and forth for tablets and laptops.
