Low-cost implementation of USB Type-C
The USB Type-C or USB-C connector interface offers a reversible cable and a flippable plug, with power delivery of up to 100W for USB 3.1 and Alternate Mode support. However, system designers must choose features carefully to keep their system’s overall cost reasonable. Many low-cost USB Type-C systems only have USB 2.0 and a native Type-C power capability of 15W. This paper highlights a one-chip solution for these Type-C implementations. The solution provides channel configuration functions with a dual-role port capability so it can be use for low- and mid-range implementation for portable applications such as smartphones, tablets, notebooks, hubs, docks, automotive infotainment, external hard disks and more.
