Integrated USB Type-C® power delivery (PD) and charging reference design for 2-4 cell batteries
Description
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 swapsComprehensive power path management and protection plus I2C capability eliminates need for 7 FETs and microcontrollerConfigurable as source/sink or sink-only powerSource mode offers on-the-go mode supportBest-in-class web-based GUI available for simple PD controller configurationWide input voltage range for charging a 2-4 cell battery at a current of up to 5 A
