Hello, I have a question.
I used an amorphous silicon solar panel AM5610.
When testing under direct halogen lamp, the cold start phase Vin is about 360mV.
In addition, yellow line is Vin_DC and green line is VBAT.
I want to know why the cold start voltage goes up until reaching to main boost mode. (3s ~ 5s)
It has to be constant until start sampling according to Figure 15. ‘Startup into Depleted Storage Element’ of BQ25504 datasheet.
I attach my measurement. Thank you!
