TPS2543 in DCP_Auto mode output voltage on/ off continute

Other Parts Discussed in Thread: TPS2543

Dear Team:

 Our customre used TPS2543 in wireless charger that USB port is on ourTUSB8041 down stream port.

When TPS2543 change to DCP_Auto mode (datasheet table 2 set 0111), output volage will turn on/ off/ on/ off continute.

When TPS2543 change to CDP_Short mode (datasheet table 2 set 1000), output volage is correct to keep at 5V.

Could you tell me why DCP_Auto mode had the behavior?
