TUSB211-Q1: External PD resistor value range of ENA_HS

Part Number: TUSB211-Q1
Other Parts Discussed in Thread: TUSB212, TUSB211

Hi Team,

My customer is trying to add an external PD resistor on ENA_HS pin. I already knew that there is an internal PD resistor of 500kohm on ENA_HS pin, but I want to know the recommended external resistor value range which can work properly. Please let me know that.

Let me explain on it. The reason why they want to replace to TUSB211 instead of TUSB212. There is an external PD resistor of 39kohm on DC_BOOST/ENA_HS pin of TUSB212.

Hi,

Since TUSB211 ENA_HS is only a output status pin external pull down of 39 kohm will have no affect on the redriving function.
