TPS25810: configuration

Part Number: TPS25810

hi teams:

1.The general fast charging protocols for TYPE C include QC3/QC2/PD3.0/PD2.0. Which protocol does TPS25810 support for TYPE C fast charging?

2. What configuration does the interface circuit need to be matched with the mobile end (mainstream mobile phones)?

The current design is that the device end is a standard TYPE C bus base, and the CC1 and CC2 pins of the base are directly connected to the CC1 and CC2 pins of TPS25810. There is no pull-up resistor or pull-down resistor configured. At present, the test uses a type C male to type C male adapter cable to connect the device and mobile phone for charging, and the device terminal TPS25810 has no output voltage. The charging current is 0, and I have tested that there should be no resistance between the internal CC of the adapter cable and ground.

Question: Do we need to configure the 5.1K resistance of CC1 and CC2 to ground on the device end? If so, what is the required resistance value of the resistor? There are options for 5.1K and 1K in the EVM reference design
