Other Parts Discussed in Thread: TPS65987,
In my design I am using the TPS65987D as a DFP provide power.
I am using GPIO#14 as a push pull GPIO to turn on and off the power supply. I am using GPIO#15 as an open drain output (no internal pull or pull down).
GPIO#14 is configured to turn on on a Port 0 plug event. This is working. When the UFP device USB-C cable is plugged in, GPIO#14 turns on as expected.
I configured GPIO#15 to turn on "port 0 PDO 1 Negotiated" event. This is not working. The open drain output seems to be turned on straight away i.e. not waiting for the PDO1 from the UFP device.
I need help fast.
Thanks.
