Product Summary

The MAX846AEEE-T is a cost－saving multichemistry batterycharger system that comes in a space－saving 16－pin QSOP. This integrated system allows different battery chemistries (Li－Ion, NiMH or NiCd cells) to be charged using one circuit. In its simplest application, the MAX846AEEE-T 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. An internal 0.5%－accurate reference allows safe charging of Li－Ion cells that require tight voltage accuracy. The MAX846AEEE-T voltage－ and current－regulation loops used to control a low－cost external PNP transistor (or P－channel MOSFET) are independent of each other, allowing more flexibility in the charging algorithms.
