Hi Sir,
My customer meet an issue about their thunderbolt docking cannot normal charging to apple MAC book in S3 stage,
When MAC book in S0 stage, thunderbolt CPU set TPS2546 CTRL1/2/3 pin to 1/1/1 to set CDP mode,
but MAC book in S3 stage, thunderbolt CPU should be set TPS2546 CTRL1/2/3 pin to 0/1/1 to Auto mode, but this time found it set CTRL1/2/3 pin to 1/1/1, it should be thunderbolt CPU control issue or it may caused by TPS2546, do you meet this issue before? TPS2546 is a passive device controlled by CTRL pin, right?
Thanks!
Jeff
