Is there an ic available from Texas for balancing 12 series connected supercapacitors?

Hello Stephen,

Looking through the catalog I do not see anything.

The closest solution I can think of would be to the BQ24640 which a supercapacitor charger that can handle strings or that size at the current and then use a passive voltage balancing scheme.

Such a scheme is dicussed on the end of Pg. 2 in this guide : http://www.illinoiscapacitor.com/pdf/EDLC%20application%20guidelines.pdf

Here is also some additional passive balancing information.

Let me know if you have any questions.
