Reduce solution size by half with new USB Type-C™ docking system design
Accelerating development of USB Type-C and PD (Power Delivery) docking stations

TI Korea (CEO Kent Tran) announced the release of a multi-port USB Type-C and PD (Power Delivery) mini-dock reference design that supports audio, USB data, power, and video.

This reference design, newly added to TI Designs, TI's reference design library, can be powered by existing power adapters, USB Type-C adapters, or laptop computers, providing end users with flexible and intelligent capabilities. It also offers a tested and verified docking solution measuring 2 x 4 inches, which is at least 50% smaller than existing docking solutions.

The core of the USB Type-C and PD mini-dock reference design (TIDA-01243) supporting video and charging is the TPS65982 USB Type-C and PD controller. The TPS65982 supports a dual-role USB Type-C port, is capable of delivering 60W of power, and supports DisplayPort and USB data transfer in alternate mode.

In addition, this reference design utilizes the TPS65986 USB Type-C and PD controller, HD3SS3212 SuperSpeed multiplexer, TUSB321 dual roll port controller, and HD3SS460 alternate mode multiplexer together to provide dual roll port functionality for power, data, and video transmission.

This reference design enables autonomous PD negotiation for both source and sink, eliminating the need for an external microcontroller. By combining the highly integrated TPS65982 and other USB Type-C components into an optimized circuit, developers can use the MiniDock reference design to develop docking stations that are up to 50% smaller than other similar existing designs.

With various output options supporting USB 3.0 or 4K resolution video and digital audio, all ICs within the design comply with current USB Type-C and PD standards, simplifying the developer's design cycle and accelerating design speed. This reference board includes port controllers, data multiplexers and DC/DC converters, load switches, field-effect transistors (FETs), signal compensation products, and circuit protection devices that meet TI's USB Type-C and PD specifications, making product selection and purchasing easier during the design implementation process.
