The TPS65987DDJ works very well in single port Notebooks that support PD charging. The two internal power paths for the TPS65987DDJ source System 5 V on VBUS through the PPHV2 path and sink VBUS up to 20 V on PPHV1. The TPS65987DDJ integrated reverse current protection allows the designer to connect PPHV1 to another power source such as a standard barrel jack or proprietary dock connector power to charge the notebook battery. The System 5-V supplies power to PP_CABLE on the TPS65987DDJ to supply VCONN to Type-C e-marked cables and Type-C accessories. An embedded controller EC is used for additional control of the TPS65987DDJ and to relay information back to the operating system. An embedded controller enables features such as entering and exiting sleep modes, changing source and sink capabilities depending on the state of the battery, UCSI support, control alternate modes, etc.
