TUSB422: Reference code for PPS

Hao Wang14

Part Number: TUSB422

Hi Team,

Is there reference code for PPS such as QC4.0 in the power negotiation? If so, could you please share the reference code, thanks!

Best Regards!

TUSB422 has nothing to do with QC, it's a PD controller

Hi Brain,

TUSB422 is the PHY for PD communication, the latest QC4.0 negotiates the power(voltage/current) through CC lines rather than D+D- in QC2.0/3.0. As TUSB422 can also send PD message with another PD controller, so I'm wondering if it can also support PPS message because PPS is part of PD3.0.

I see, TUSB422 was developed before QC4.0
