Recommendation for battery charger needed

Other Parts Discussed in Thread: BQ24171

Team, since my local FAE is out for the holidays, i hope you can help. 

I have a customer whom we have been working on a design, that requirements have recently changed. Here are the details:

We have tentatively made the decision to change the power supply feeding the charger from a 12VDC supply to one which provides 24VDC.  That being said, does TI offer a comparable solution to the bq24171 with a higher input operating voltage? 

Requirements:

  • 2 or 3 Li-Ion series cells that will need to charge at 3.9A for the 2 series or 2.6A for the 3 series. 
  • We would like the option to set the charge voltage and current using external components and not require a micro and code in order to do this.  

Thanks
