To test the TIDA-050047 reference design after the configurations have been programmed, there are a few connections that need to be made before powering on.

First, the TIDA-050047 needs to be powered on. To provide the necessary power required to power on the TPS25750D for sourcing and the BQ25798, a bidirectional power supply can be connected to the BATT socket at J2. Depending on the cell configuration jumper settings for JP1 – JP3, the voltage on the power supply can be set accordingly for the voltage and up to the current limit desired, 1 A is sufficient for testing. The JP4 jumper also needs to be populated for the default thermistor settings.

Once the connections are properly made, the power supply can be turned on. The power supply on BATT, powers on the BQ25798 and the necessary 5-V and 3.3-V buck converter and LDO that connects to the TPS25750D. Once the PD controller is powered on, the controller loads the project configurations that were programmed on the Flash IC to operate based on the selected options in the Application Customization Tool.

The TIDA-050047 is now ready to be connected to a port partner via a USB Type-C cable to either source power or the sink power as negotiated.

To test a sink-only application, such as in dead battery mode, the same connections can be made, except this time, you do not need to supply power on the BATT pin, instead, it sinks power to simulate charging a battery. Therefore, once the correct jumpers are set, when the USB Type-C cable connects to a port partner that offers Source capabilities, the TPS25750D powers on using VBUS and loads the proper configurations from the Flash to program the BQ25798 for charging the battery.
