Yep, I've been looking at the Maxim charger chips that setup up to work with a uControllers.  I have yet to run across any others.

I have a Duracell 15 minute NIMH charger, and was wondering why it killed batteries so fast.  After reading up on the charging methods for the different chemistries, now I know why.
