Product details

Single-cell battery monitor in a compact SOT-23-3

The MAX6427EHUR-T from Analog Devices (Maxim Integrated) is a single-cell battery monitor IC designed to work with multi-chemistry battery types. 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.

Frequently asked questions

Can MAX6427EHUR-T be used with lithium-ion batteries?

Yes, the MAX6427EHUR-T supports multi-chemistry battery types, which includes lithium-ion cells. It is designed to monitor a single cell, so it works with a 1S lithium-ion configuration.

What are equivalent alternatives to MAX6427EHUR-T?

No pin-compatible equivalent is listed in the available records. The SOT-23-3 package is a common footprint, so functionally similar single-cell battery monitors from other manufacturers may be layout-compatible, but pin-to-pin compatibility requires direct cross-reference verification.
