kdklol: I was recently searching for NiMH charging ICs, turns out they basically don't exist. Most devices which charge their NiMH batteries implement low CC charging, which is slow. It's a shame, because NiMH batteries do have their advantages (safety, ease of finding replacements, etc.) and can be recharged fairly quickly if the charger is smart enough.

cmbuck: What do you mean by "they basically don't exist"? Solutions like the TI BQ25172 are designed exactly for this purpose.

Liftyee: I have done similar searches before. They do exist, but most dedicated ICs are targeted towards tightly-integrated cells or battery packs. The variety available is much smaller than for Li-ion batteries, and the ICs are more expensive.It seems like commercial multi-cell battery chargers mostly use custom microcontrollers to achieve this, instead of multiple charging ASICs.
