TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 10.1 Application Information The typical applications of the TPS65982 include chargers, notebooks, tablets, ultrabooks, docking systems, dongles, and any other product supporting USB Type-C, USB-PD as a power source, power sink, data DFP, data UFP, or dual-role port (DRP), or supporting both USB Type-C andUSB-PD. The typical applications outlined in the following sections detail a Fully-Featured USB Type-C and PD Charger Application and a Dual-Port Notebook Application Supporting USB PD Charging and DisplayPort. 10.2 Typical Applications 10.2.1 Fully-Featured USB Type-C and PD Charger Application The TPS65982 controls three separate power paths making it a flexible option for Type C PD charger applications. In addition, the TPS65982 supports VCONN power for e-marked cables which are required for applications which require greater than 3 A of current on VBUS. Figure 77 below shows the high level block diagram of a Type C PD charger that is capable of supporting 5 V at 3 A, 12 V at 3 A, and 20 V at 5 A. The 5 V and 12 V outputs are supported by the TPS65982 internal FETs and the 20-V output uses the external FET path controlled by the TPS65982 NFET drive. This Type-C PD charger uses a receptacle for flexibility on cable choice. Figure 77. Type-C and PD Charger Application 10.2.1.1 Design Requirements For a USB Type-C and PD Charger application, Table 11 lists the input voltage requirements and expected current capabilities. |
