It is not a fuel gauge — there is no coulomb counting or remaining-capacity reporting. It is a simple voltage monitor that pulls an output low when the cell drops below its trip point, suitable for undervoltage lockout or low-battery warning in portable equipment. The industrial temperature range (-40°C to 85°C) covers outdoor handhelds, IoT endpoints, and battery-backed instrumentation, but stops short of automotive under-hood or engine-bay environments. ## Package and footprint — SOT-23-3 Supplied in a SOT-23-3 package (also listed as TO-236-3 or SC-59), this is a three-pin surface-mount device with a standard 2.9 mm × 1.3 mm body and 0.95 mm pitch. No thermal pad, no exposed paddle — just three solder joints and a small PCB footprint. The shipping form is Bulk (tube or loose parts), not Tape & Reel, so factor that into your pick-and-place setup or plan a tube-to-reel transfer for volume assembly. ## Lifecycle and sourcing — active, no LTB pressure The MAX6427DHUR+ carries an Active product status per the manufacturer's latest lifecycle record.","metaTitle":"MAX6427DHUR+ Battery Monitor, SOT-23-3, Active","metaDescription":"MAX6427DHUR+ single-cell Li-ion/polymer battery monitor in SOT-23-3.
