Hi Jan,

I am able to find any information on that device, either. It is probably an obsolete device. I would suggest you choose another part.

I have malfunctioning BMS with this BQ30472, Its running 3x3 LG LiPo. It is dated 2014/07. Does not sound like it is obsolete chip....

Just for some reason nowhere I can find any info as well. Weird.

Does anyone knows any chips that are similar or are modern replacement ?

What is the target equipment and battery model which uses that IC

For some reasons there is no fully compatible equivalent IC but the nearest to pins configuration is TSSOP-38 bq3050 gas gauge.
