Hello,
Here are few questions related to the device parameters that need to be selected in EZ-PD Configuration Utility.
1. In table Port Information what is the parameter Current Level? Is it the source or the sink current? Our port is dual dual role power.
2. In table Port Information what is the parameter Rp supported? Is it the termination resistor that tell the device what the maximum source current is? What the difference between 1.5A and Default 1.5A is? Our port can source 1.5A maximum.
3. In table Sink PDO 0 what is the parameter Higher Capability? When the device need more than 5V to support full functionality should we set that parameter to Yes or to No?
Thank you
Best Regards,
Patrice

Hi Patrice,
1. It specifies the Current level to be used as Source (Rp value).
2. Rp is the termination resistor to tell the device the maximum source current when its not in PD contract.
Default in this refers to Default USB Power allowed. If the USB connection is USB 2.0 then max current is 500mA and if its USB 3.0 its 900mA. That's the reason particular current value is not specified instead its mentioned as default. If your Device supports 1.5A you can set it as Default - 1.5A.
3. If your device is sinking power and would require more than 5V you should set this to Yes and add another Sink PDO with higher capability.
Please let me know if you need any further information.
