It monitors cell voltage and provides an alert or control signal when thresholds are crossed — typical for over-discharge protection or low-battery warning in portable equipment. The industrial temperature grade (-40°C to 85°C) suits outdoor, automotive cabin, or factory-floor applications where the battery pack sees ambient extremes. ## Package and mounting Housed in a SOT-23-4 package, surface-mount only. The four-pin footprint is small enough for tight PCB layouts in handheld or embedded battery management boards. ## Lifecycle and compliance One important caveat: the part is RoHS non-compliant. If your BOM must meet EU RoHS or similar restricted-substance directives, this part will not pass. For legacy or exempt applications, that is not a blocker.","metaTitle":"MAX6431DHUS-T Battery Monitor, 2-Cell, SOT-23-4, Active","metaDescription":"MAX6431DHUS-T multi-chemistry battery monitor for 2-cell packs.
