Product Summary

The MAX846AEEE is a cost-saving multichemistry batterycharger system that comes in a space-saving 16-pin QSOP. The MAX846AEEE allows different battery chemistries (Li-Ion, NiMH or NiCd cells) to be charged using one circuit. In its simplest application, the MAX846AEEE is a standalone, current-limited float voltage source that charges Li-Ion cells. It can also be paired up with a low-cost microcontroller (μC) to build a universal charger capable of charging Li-Ion, NiMH, and NiCd cells.
