Need suggestions for 2 cell rechargeable Li-ion application?

Hi Folks,

 

I'm at the beginning of a project that needs a battery charger chip for a 2-cell (18650 Li-ion cells) application.  The batteries won't be replaceable.  I found the LTC4162 chip but will I also need a cell balancing function?  So my question is: will the LTC4162 work best?  I have a micro-controller in the system so the i2c connection shouldn't be a problem.

 

Bonus points - any suggestions for a coulomb counter chip that might work with the charger chip?

 

Thanks in advance,

 

Richard
