TPS2546-Q1: TPS2546-Q1 Status pin output

Part Number: TPS2546-Q1

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
