Single-cell battery monitor in a SOT-23-3 footprint
The MAX6428ORUR+ is a single-cell battery monitor from Analog Devices that supports multi-chemistry types — Li-ion, NiMH, alkaline, or lead-acid — without needing a chemistry-specific configuration pin or register. Housed in a SOT-23-3 package (TO-236-3, SC-59), it occupies minimal board area and suits space-constrained portable or handheld designs where a dedicated fuel-gauge IC would be overkill.
