BQ24171: Li-Ion 2S3P Battery Design Check,

Part Number: BQ24171
Other Parts Discussed in Thread: BQ29209

Tool/software:

Hi, TI E2E

I want to design a Li-Ion battery, but I'm uncertain if the design need to do any more modify?

The design need to do the IEC-62133 verification.

The design is refer from each component datasheet or EVB.

0.Li ion use: Samsung INR18650-35E, 2 Series 3 Parallel, 0.5C (max charging current<4.95A) 

1.battery balance and protect IC use: BQ29209DRBR,

2.battery charger IC use: BQ24171RGYR

    In this design set as 4A, could modify the output L and C to config the charging current

3.buck IC use: TPS566247DRLR (6A)

    The total current from the load(SBC,FAN,HMD) is 5A(peak), could I just use one of this buck?
