HUSB311 helps realize domestic USB Type-C port

    According to Bloomberg news, the relevant domestic institutions and units in the next 2 years to complete a total of 50 million units of domestic computer replacement. From hardware to software, the call for localization is getting higher and higher, and the trend of localization is unstoppable. Behind the rapid development of the localization market is the improvement of the domestic technology level. As a domestic brand, Hynetek Semiconductor has the core technology of fully independent IP, and its products have absolute competitiveness in China as well as globally. Facing the market demand of 100% domestic computers, Hynetek can provide high-performance domestic USB Type-C interface solutions.

    The HUSB311, also known as Type-C Port Controller (TCPC), is compliant with the latest USB Type-C and PD 3.1 standards and can be extended to support Data Role Swap and Power Role Swap. It can be extended to support Data Role Swap and Power Role Swap protocol commands for power switching and data communication switching products, such as laptops, projectors, cell phones, etc. Currently, HUSB311 has been shipped in large quantities in Xiaomi, Samsung and other end products.

PD DRP Application Solution

    The circuit in the following figure is suitable for the battery charging and discharging and data channel control in DRP dual mode. The application processor (AP) or embedded controller (EC) controls the HUSB311, and then the battery charger and USB data switch are controlled based on the information from the HUSB311. In addition, similar products in the market include FUSB302, RT1715, RT1711 and TUSB422, etc. The HUSB311 is pin compatible with all of them and the software programs of TCPM are similar.
