4 Validation Tests

Port Advertisements test

Connect a PD trigger to the output Type-C port. The trigger will show the available PD contracts advertised by TPS2674x-Q1. These will match the GUI configuration as long as an over temperature or input voltage protection mechanism is not active.

Load test

Connect a PD trigger to the output Type-C port and an electronic load from VBUS to GND. Negotiate a desired contract using the PD trigger, then increase the load. The load will be supported indefinitely as long as a protection mechanism does not activate.
