Other Parts Discussed in Thread: BQ27220
Hello,
From datasheet, it looks both part can be used for Lithum-Ion detection.
But BQ27621-G1 is more simple without external resistor.
I am not sure any disadvantage of BQ27621-G1. Please suggest.
My application:
1) 4 x NCR18650B Lithum Ion Parellel package.
2) Charge current 3.3A

4) Use for battery measurement tp estimate the left battery for handle device. Such as 10% battery left,
