Part Number: BQ29706
Hello,
I want to use BQ29706 and BQ29200 for 2S1P configuration of lithium iron phosphate (LFP) battery. I have few questions regarding this:
Q1: As a LFP has upper voltage limit of 3.65V, can I use BQ29706 (OVP=3.85v) for cell protection?
Q2: If yes, can I scale this configuration to 2S1P by adding two similar configurations as used in Q1?
Q3: Can BQ29200 (2-cell balance IC) be used in cell balancing of configuration used in Q2? As the battery I want to use is LFP battery whose nominal voltage is 3.2v, however, the IC BQ29200 is for 4.2v. Since the IC BQ29706 has already over-voltage protection, can this BQ29200 be used for balancing without using its over-voltage protection feature?
Thanks!
