TPS65982: Actions updating source PDO

Part Number: TPS65982

Hi all,

 

If TPS65982 is a source, active PDO is 5V/3A, and a microcontroller updates the source capability to 5V/2A, then it has to handshake again to adjust the contracted power to 5V/2A. Then what would be the proper action for this?

I have seen 5V/2A is contracted if the microcontroller sends SSrC command to TPS65982 after updating the source capability. Would it be the right way to update the source capability and make them contract again?

 

Best regards,
