5 Configuring the TPS25750EVM

The TPS25750EVM can be programmed using the TPS25750 Application Customization Tool, which is a web based GUI. The configuration of the TPS25750 is controlled via this GUI, and programming the EVM is also done using this GUI. Once the web GUI is opened, follow the questions to match the EVM configuration. The first option asks to select the power path configuration, select the figure labeled "EVM", shown below.

Questions 2 through 4 go through source and sink power and power role. Here the default source and sink power were chosen to match . The EVM's out of box power role is a source. Question 5 through 8 go through additional questions. There is not a preferred data role on the EVM. There is no USB data on this EVM, the Vendor ID will be TI's Vendor ID, and the desired Product ID may be left as "0x000".

The battery charger section must have the BQ25731 selected with the correct voltage and current. The BQ25731 has its charging current set in 0.128 A steps due to bit resolution. For a 12 V 3 A application, the 3.072 A will be an appropriate charging current.

Once the configuration has loaded, connect a Type-A cable to the Micro-B connector, J11 and your laptop. Make sure that the entire EVM is powered by connecting 20 V to either the barrel jack or the SYS_PWR test point. Once the Type-A cable has been connected, and power is provided to the EVM, you may flash the configuration from the GUI onto the EVM. Navigate to the right side of the page, which has the different file generation and flash options. Select "Flash To Device From Current Configuration" to load the settings onto the EVM.
