Hi Kyle,

If the Active means turn on the VBUS consumer, you are correct, the VBUS_C_CTRL is drive HIGH for enable it.

Hi Lisa,

I think active low can't turn on consumer path of CCG6SF.

CCG5C is PFET gate driver, and CCG6SF is NFET gate driver.

I need your confirmation.

Hi Lisa,

Active means turn on VBUS consumer path, so that Type-C power adapter or dock can charge the laptop with CCG6SF/DF.
