But i need to know wich ic chip will work for me…
Thank you…
Hello,
Thank you for your post.
I’m sorry, but I am not able to verify that chip. It is likely a proprietary chip if it was built into something that was mass produced.
It is OZ7714SN, SSOP-24.
OZ7714SN integrates O2Micro’s BODTM (Balance On Demand) patented technologies, providing maximum energy per charge and longest cell cycle life. The maximum internal cell balance current is 25mA per cell.

With the information @adam7 gave I found the BQ33100PWR as a 24 pin surface mount battery balancer.
It may work. If you are able to find a data-sheet for the original you can review the specs for that vs what the BQ33100PWR has.

Here’s where you can find a minimal datasheet for that part. As far as I can tell, we don’t sell a drop-in sub for his part.
