TPD6S300A: Is there a way to control the tON_FET_DB?

Part Number: TPD6S300A

Tool/software:

Hi,

As per the datasheet tON_FET_DB max is 9.5ms, which is the time taken to turnoff the Rd resistance path after the VPWR is detected. Is there a way to increase this time? Is this time enough for the PD/CC controller to advertise current from the source.

Hi Anoop,

Thank you for reaching out!

Which PD controller is being paired with the TPD6S300A? What is the power role of the PD controller?

Best Regards,

Aya Khedr

We are using a 3rd party PMIC with USB PD PHY 3.0 support. The role of the PD is DRP.
