TPS65987D: GPIO Event for disabling internal source switch

David Korecek

Part Number: TPS65987D


Hello,

does TPS65987D have a specific GPIO event for disabling the internal source switch? My implementation is like a notebook, Alt. mode, power sink 12-20V/5A, power source 5V/3A. I would like to control (enable/disable) the USB source switch in the system power states S3/S4/S5. I have checked document "TPS65987D GPIO Events" but there I found only "Sink Arbitration GPIO Input".

Thank you.

Best regards

David

    Hi David,

    We do not have a GPIO event for this. However, you could open and close the sink switch through a Host EC by using the SRDY and SRYR 4CC commands. You could find more information on these commands in the host interface TRM:
