Packaged in a SOT-23-3, it fits into space-constrained portable or battery-backed equipment where board area is tight. The operating temperature range of -40°C to 85°C covers most industrial, outdoor, and automotive cabin environments, so it can sit on a BMS board inside a battery pack or on a handheld device mainboard without thermal concern. ## What the single-cell rating means for fit The part monitors exactly one series cell. For a single-cell Li-Po or Li-ion cell, it is a direct fit. The multi-chemistry support allows use across product lines that switch between chemistries, simplifying inventory. ## Package and mounting — SOT-23-3 surface mount The SOT-23-3 (TO-236-3 / SC-59) is a common three-lead footprint. The supplier device package is SOT-23-3, and the shipping medium is Bulk — not Tape & Reel. If your pick-and-place line expects reeled parts, verify the feed method; Bulk parts may require manual placement or a tube feeder adapter. Surface-mount soldering follows standard reflow profiles for small-outline transistors. ## Lifecycle and compliance It is marked RoHS non-compliant, so if your assembly line or target market requires RoHS exemption documentation, factor that into the BOM review.","metaTitle":"MAX6429EHUR-T Battery Monitor, SOT-23-3, Active","metaDescription":"MAX6429EHUR-T single-cell multi-chemistry battery monitor in SOT-23-3.
