Hi team
Hope this email finds you well.
MY customer XINJE(NO.1 PLC factory in china) is testing BQ25601EVM board, Could you please these two question:
1. Can register saved when power off?
2. Vsys (TP4 (SYS), TP8 (GND)) is jump between 3.76V~4.2V, when there is no load between Vbat and GND, ?
About the question 1, I couldn't find any evidence that show the register can be saved after power off in datasheet, can we?
About the question 2, I tested the EVM also, and found that
When I "Disabled Terminaton ", the load of EVM board is stable in 0.11A, Vsys is stable in 4.2V.;
When I "Enable Termination", the load of EVM board is jump between 0.01A~0.11A,the Vsys is junp between 3.7V~4.2V as below picture.
After I watched the datasheet 8.3.7.3 Charging Termination, still got no clue about this. Could you please help explain the reason?
Thanks Irene
