This reference design features charging up to 20 V at 5 A without the need for any external FETs, enabling a much smaller solution size and reducing total BOM cost. A microprocessor is also not necessary as the TPS25750 power delivery (PD) controller will handle the I2C communication to the BQ25792 battery charger IC. This I2C capability and the TPS25750 web-based GUI greatly simplify the firmware development process.
Features
Supports standard Type-C communication, PD negotiation, and power/data role swaps
Comprehensive power path management and protection plus I2C capability eliminates need for 7 FETs and microcontroller
Configurable as source/sink or sink-only power
Source mode offers on-the-go mode support
Best-in-class web-based GUI available for simple PD controller configuration
Wide input voltage range for charging a 2-4 cell battery at a current of up to 5 A

Step 2: Download the Symbol and Footprint from the CAD.bxl file table.
Texas Instruments and Accelerated Designs, Inc. have collaborated together to provide TI customers with schematic symbols and PCB layout footprints for TI products.
Both PCB footprints and schematic symbols are available for download in a vendor neutral format, which can then be exported to the leading EDA CAD/CAE design tools using the Ultra Librarian Reader. The reader is available as a (free download.).
The UL Reader is a subset of the Ultra Librarian toolset that can generate, import, and export components and their attributes in virtually any EDA CAD/CAE format.
