USB Type-C controller handles data and power

The TPS65982 USB Type-C and power delivery controller integrates a port power switch and port data multiplexer. It supports data as a downstream- or an upstream-facing port, provides cable plug and orientation detection, and communicates on the CC wire using the USB PD protocol.

 When cable detection and USB PD negotiation are complete, the IC enables the appropriate power path and configures alternate mode settings for internal and (optional) external multiplexers. The mixed-signal front end provides 0.5, 1.5, or 3 A for Type-C power sources. The port data multiplexer passes data to/from top or bottom D+/D– signal pair at the port for USB 2.0 HS, and has a USB 2.0 Low Speed Endpoint. Data rates as high as 5.4-Gbits/s can be obtained with using a HD3SS460 cross-point switch IC. The TPS65982 comes in a 6 x 6-mm MicroStar Junior BGA package and costs $4.99/1,000.
