TPS25750: How to reset PD connection?

Part Number: TPS25750


Hello team,

We would like to know how to reset PD connection using TPS25750. Currently, we are facing an issue that, when Nintendo_Switch is connected to TPS25750EVM, it is connected as Source (this is expected). However, when 20V adapter is connected to TPS25750EVM, Nintendo_Switch will always reject Power Role Swap and causing a connection issue. We need TPS25750EVM to be Source after 20V adapter is connected.

Therefore, we would like to know how to reset PD connection after 20V adapter is connected to TPS25750EVM such that TPS25750EVM will become the Source.

Please advice.

Thanks.
