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.

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.

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.
