BQ4050: BQ4050 functional question

Part Number: BQ4050
Other Parts Discussed in Thread: BQ29330,

Hi Team,

My customer has some BMS application concern wonder to be resolve.

 

The situation is their battery side have to has BMS function , so their battery supplier provide his exist solution is the BQ20Z60 + BQ29330.

 

But we suggest them to use BQ4050 , Is it the same function for BMS ? BQ4050 is better option to replace old one(BQ20Z60 + BQ29330)?

 

If it is true , the gauge IC is need to  layout on the battery side, right ?

 

Please help us to understand this application issue , thank a lot!
