MAX846AEEE+ Datasheet PDF - Maxim Integrated

The MAX846AEEE+ is a cost-saving, multichemistry battery-charger in 16 pin QSOP package. This integrated system allows different battery chemistries (Li-Ion, NiMH or NiCd cells) to be charged using one circuit.MAX846A is a stand-alone, 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. It has a built-in 1%, 3.3V, 20mA linear regulator capable of powering the µC and providing a reference for the µC"s analogue to digital converters. Typical applications include battery packs and hand held instruments.
