Other Parts Discussed in Thread: TPS25750
Hi,
I have an adapter whose photo is attached below.
Thanks to this PD adapter, I can get various voltage and amperage values. I want to charge the battery by using 20V and 1.5A with this adapter on the USB-PD-CHG-EVM-01 card I use. However, when I compared the PDO values I set in the Transmit Sink Capabilities section in the advance options section of the GUI with the values coming from the adapter, I saw that they were not the same. When I measured the voltage coming from the PD adapter, I saw that it did not exceed 12V. Below is the JSON code of the settings I set via the GUI.
{"questionnaire":{"version":"7.0.4.7","answers":[4,null,3,null,0,null,1,null,1,null,0,8.4,1.5,0.4,0.4],"options":{},"configID":"0000","vendorID":"0000"},"configuration":{"data":{"selected_ace":[{"register":6,"data":[0,0,0,0,0,0,0,0]},{"register":22,"data":[10,48,48,77,0,0,0,0,0,0,3]},{"register":50,"data":[0,168,42,44,145,1,38,44,209,2,0,44,177,4,0,244,65,6,0,0,0,0,0,0,0,0,0,0,0,0,0]},{"register":51,"data":[4,44,145,1,16,44,209,2,0,44,177,4,0,44,65,6,0,69,65,6,0,0,0,0,0,0,0,0,0]},{"register":92,"data":[48,0,0,0,0,0,0,0,0,16,0,0,0,0,0,0,48,0,0,0,0,0,0,0,0,12,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]},{"register":117,"data":[0,0,0,0]}]}}}
When I set it to 9V via the GUI, I see the voltage coming from the PD adapter as 9V. But when I set voltage values such as 15V or 20V, only 12V comes from the adapter. Considering that there might be a problem with the PD adapter, I connected my adapter to another PD controller card and set the PD controls to 20V.
As can be seen above, 20V voltage can come from the adapter. Therefore, I thought the problem might be caused by TPS25750. How can I set the TPS25750 to the voltage value I want or what is the solution to this problem?
Best regards.
