Part Number: TUSB321
Hi All,
Regarding the VBUS_DET pin, is it better to pull up the pin when using it with DFP?
The recommended pull-up resistor is 900kΩ. 900kΩ is not used much.
Does it need to be 900kΩ? Is it okay to open?
Best Regards,
Ishiwata

Hi Mr. Ishiwata,
When you're configured for DFP only mode, you can leave VBUS_DET open. Here is the section of the datasheet describing this:
