Housed in a surface-mount SOT-23-3 package, it provides undervoltage/overvoltage monitoring for a single cell, making it a space-efficient choice for portable and battery-backed systems. Its industrial temperature range of -40°C to +85°C suits it for environments from outdoor telecom to automotive cabin applications where a single lithium-ion, LiFePO4, or other chemistry cell needs a supervisor. ## What the ratings mean for your BOM The multi-chemistry support means this part isn't locked to a specific cell type — it can monitor lithium-ion, LiFePO4, NiMH, or lead-acid single cells, which simplifies inventory if your designs span chemistries. The single-cell count is a hard limit: this part monitors exactly one series cell, so a 2S or higher pack needs a different monitor or a stacked configuration. The SOT-23-3 footprint is a standard, widely second-sourced package, so PCB layout is straightforward and alternate sourcing is realistic if volumes justify qualification. ## Lifecycle and sourcing posture This removes the LTB risk for new designs and ongoing production. The part is RoHS non-compliant, which is a flag for EU or similar regulatory markets — verify your exemption coverage or plan for a RoHS-compliant alternate if needed.","metaTitle":"MAX6427EHUR-T Battery Monitor IC, Multi-Chemistry, SOT-23-3","metaDescription":"MAX6427EHUR-T single-cell battery monitor from Analog Devices (Maxim).
