9 Application and Implementation

Note

Information in the following applications sections is not part of the TI component specification,

and TI does not warrant its accuracy or completeness. TI’s customers are responsible for

determining suitability of components for their purposes, as well as validating and testing their design

implementation to confirm system functionality.

9.1 Application Information

The TPS25751 is a stand-alone Type-C PD controller for power-only USB-PD applications. Initial device

configuration is configured from an external EEPROM through a firmware configuration bundle loaded on to

the device during boot. The bundle is loaded over I2C from an external EEPROM. The TPS25751 firmware

configuration can be customized for each specific application. The firmware configuration can be generated

through the Web Tool.

The TPS25751 is ideal for single port power applications supporting the following PD architectures.

• Designs for both Power Provider (Source) and Power Consumer (Sink)

• Designs for Power Consumer (Sink)

An external EEPROM is required to download a pre-configured firmware on the TPS25751 device through the

I2C interface.

The TPS25751 firmware can be configured using the Web Tool for the application-specific PD charging

architecture requirements and data roles. The tool also provides additional optional firmware configuration that

integrates control for select Battery Charger Products (BQ). The TPS25751 I2C controller interfaces with the

Battery Chargers with pre-configured GPIO settings and I2C controller events. The Application Customization

Tool available with the TPS25751 provides details of the supported Battery Charger Products (BQ).
