TUSB521-Q1: CTL0 low clarification

Part Number: TUSB521-Q1

Hi Team,

I have a question regarding the Redriver TUSB521-Q1: after ESD testing we found out that CTL0 pin of the redriver is pulling to low despite having and external pull-up.

While the redriver FLIP pin is functioning normally.

 

  • Apart from Average active power USB only mode and No device connected, should we see CTL0 go low, or it should be fully high for normal operation?

 

Thanks,

David
