We are evaluating our board of TPS65987DDH but a problem occurs.
We would like to know the cause and workaround.
1.After turning on the power to the IC, set Transmit Sink Capabilities(0x33) by I2C.
*Operating current of 0x33 is from 0.9A to 1.5A.)
2. If read operating current of 0x33 by I2C, I can read 1.5A so write by I2C is correct.
3. However, if read 0x33 by USB PD analyzer, Operating current of 0x33 is 0.9A.
4. Source side is sending source capabilities but no response form Sink side.
It looks like Source side keeps sending source capabilities information.
Could you please let us know if you have any concern and workaround?
(For example, 0x33 changing timing, sequence etc.)
