TUSB4041I: OTP port polarity configuration tool

Florian Perget

Part Number: TUSB4041I

Tool/software:

Hi,

I have accidentaly crossed the DP and DN lines on two downstream ports of on a PCB design. I would like to salvage those cards by setting the polarity on these two ports, but I did not include an EEPROM as I don't need it otherwise.

Could someone give me access to the TUSB4041I OTP software to set those bits?

Thanks and regards,

HI Florian:

Can you use SMBUS for your application?

I can send you OTP software tool, but it's just for your debug, I'm not sure you are going to configure hub by OTP manually for every device.

Thanks for your quick reply.

I have already fixed the issue in CAD for the full production. The other two downstream ports work fine, I have 5 pre-production PCBs I want to validate the rest of the system design with.

Regards,
