2-cell multi-chemistry monitor in SOT-23-8
The MAX6849KASD3-T is a battery monitor IC from Analog Devices designed to track the state of a 2-cell battery stack. It supports multi-chemistry configurations, meaning the same part can handle Li-ion, NiMH, or alkaline chemistries without a hardware change — useful when a BOM must cover multiple product variants or when the cell type is not finalised at layout.
Note the RoHS compliance status: this part is listed as RoHS non-compliant.
Sourcing and package fit
The SOT-23-8 footprint is a standard small-outline transistor package with 1.27 mm pitch — the same land pattern serves many general-purpose ICs, so a PCB already routed for a similar monitor or supervisor can often accept this part without a board spin.
