If the Vref and Vdef are not used, can they be left as NC or do they need to be connected to GND?
The datasheet doesn't mention that

I was looking for information about these pins. In order to save space, is it possible to measure the Vdet directly and not use the temperature compensation? Is there any guidelines of how to use this power detection feature? I would like to know the voltage ranges and equivalent powers if possible.
Thanks in advance!
It is possible to measure the diodes directly. Attached is the circuit you would need to use. This is the circuit present on the evaluation board and also used to create the data sheet plot. You need to measure the VREF diode voltage and the VDET diode voltage and subtract them to maintain the temp compensation. THe VDET voltage varies from -1.47 V to +0.9V. VREF is ~ 0.9 V
