hello:
When we conducted the power-off restart experiment on gauge ic (BQ27426),The following exceptions are found in the fcc:
When the battery is idle（no charge and no discharge）, if the gauge ic is powered off and restarted, the fcc has a large difference before and after the ic restart
The test steps are as follows:
1.The fcc value is read from the ic(value is 865)
2.Power off Gauge ic
3.wait 10ms
4.Power on Gauge ic
5.wait 300ms
6.load FlashStream file
7.The fcc value is read from the ic(value is 698)
What is the reason for the big difference between the fcc before and after the ic restart?
After many experiments, we found that by increasing the delay time in Step 5 to 3000ms,
The fcc before and after the restart is basically the same, is this solution feasible?
If so, is there a theoretical basis? If not, are there other solutions?
The above description can be seen in the following figure:
