7.4.7 BC 1.2 Battery Charging Controller

The TUSB216I main function is a signal conditioner offering the boost and pre-equalization features to the incoming DP/DM signals. For applications in which USB host or hub does not provide USB BC charging controller functionality, the TUSB216I can perform this task when CDP_ENZ is low and BC 1.2 CDP Controller is enabled. When battery charging CDP controller feature is enabled (CDP_ENZ=low) TUSB216I supports CDP charging downstream port functionality. CDP_ENZ has an internal pull up when the pin is left unconnected CDP controller will be disabled.
