My measurement at pin 17 (PA7) with DPS5020 stock firmware:
0.00A -> 0.059V
0.01A -> 0.060V
0.1A -> 0.070V
0.5A -> 0.117V
1.0A -> 0.176V
2.0A -> 0.293V
5.0A -> 0.645V
10A -> 1.232V
20A -> 2.400V
The pull-up resistor R17 = 2.7 Mom
Check the pull-up resistor. I think the SGM8582 will not be able to work if the input voltage is less than 0.05V.
