Hello team,
The customer uses TPS2546-Q1. However they would like to use it without USB line (DP/DM).
They set the following as below.
CTL1:H
CTL2:H
CTL3:H (CDP Mode)
ILIM_SEL :H
DM_OUT/DP_OUT:Open
DM_IN/DP_IN:Open
ILIM_LO:Open
ILIM_HI:PU(19.1kohm)
In this case, when they checked the status pin(9pin of TPS2546-Q1) at the no load of power line which means that USB device is disconnected, they saw that Status of some TPS2546-Q1 is High level others is Low level.
The customer do not use USB line (DP/DM). in this case, we can not check the specification of TPS2546-Q1 ststus from the datasheet. Would you please advise me how TPS2546-Q1 status pin behaves.
Best Regards,
Akihisa Tamazaki
