NiMh switch-mode charger for 6-cell NiMh
Any other battery charging ICs I should consider?


This one is worth a look. I'm not saying it is better, it is a switcher and appears simple.

The TI BQ24115 appears to be capable and not too complex with minimal external components given the feature set.  

For NiMH you would need the "System-Controlled" (i.e. host controller) version.  It cannot do NiMH as a stand alone charger.
