Hi Expert,
I find some difference between TPS55289-Q1 datasheet and real test wave about I2C communication. Below is the photo. When I set the delay time between "ack" and "DATA" as datasheet time sequence, the communication is failed. I capture the test timing sequence through GUI to EVM, there is no delay between "ack" and "DATA". Can you pls explain this difference? What is the meaning of the delay in the red box？
