Hi team,
What's the behavior of TPS25840-Q1's DP and DM after BC1.2 negotiation is done? Is there still communication data transmitted?
Thanks!

It determines by data sink and source handshaking process.
BC1.2 is one charging protocol instead of data communication protocol.
So it doesn't interfere data communication between device and host.
Hi Ziv,
If we assume there is no USB communication between host and device, only BC1.2 charging, how about the DP and DM behavior after negotiation?
Thanks!
DP/DM should be zero voltage potential.
