SLVSER3A November 2018 – April 2020 TPS65982BB
PRODUCTION DATA.
The TPS65982BB will route the USB2 paths from two USB Type-C ports and provide VBUS with over current protection to a USB Type-A receptacle or a USB Hub. The TPS65982BB implements a “first come – first serve” with the two USB2 paths, where the USB2 connection to the USB Type-A or USB Hub is connected to the USB Type-C port that was connected first. The device will maintain that connection until all connections are removed. When the PD controller fails to enter an alternate mode, the PD controller will communicate to the TPS65982BB through I2C to enable the billboard function. Upon receiving the I2C command, the TPS65982BB will connect its USB endpoint to the connected Type-C port and will be able to send the proper billboard message. The block diagram below shows the system application for billboard support for two Type-C ports.
