Other Parts Discussed in Thread: CSD17570Q5B, BQ24600
Configuration is as follows:
1. Using 4S1P lipo cells 8000mah
2. Load used while discharging of 7A
3. CSD17570Q5B (30V, 100A) as CHG and DSG FET
After charging the battery using BQ24600 as charger, I discharged the battery using 7A load.
Under voltage threshold was set at 3300mv per cell, So once it reached below threshold DSG FET is triggered OFF and SafetyStatus[CUV=1.
I removed the load but output at pack voltage is showing almost same as input voltage and when I again enabled DSG FET it shows twice of input voltage at output.
This happened twice. Can you help in finding the issue as when I partially discharge then this issue does not come.
I have attached the image of protection FETs.
