Product details

Single-cell battery monitor in a three-pin SOT-23-3

The Maxim Integrated MAX6429EHUR-T is a battery monitor IC designed to supervise a single cell across multiple chemistries — Li-Po, Li-ion, NiMH, NiCd, and others. Packaged in a SOT-23-3, it fits into space-constrained portable or battery-backed equipment where board area is tight.

What the single-cell rating means for fit

The part monitors exactly one series cell. For a single-cell Li-Po or Li-ion cell, it is a direct fit. The multi-chemistry support allows use across product lines that switch between chemistries, simplifying inventory.

Package and mounting — SOT-23-3 surface mount

The SOT-23-3 (TO-236-3 / SC-59) is a common three-lead footprint. The supplier device package is SOT-23-3, and the shipping medium is Bulk — not Tape & Reel. If your pick-and-place line expects reeled parts, verify the feed method; Bulk parts may require manual placement or a tube feeder adapter. Surface-mount soldering follows standard reflow profiles for small-outline transistors.

It is marked RoHS non-compliant, so if your assembly line or target market requires RoHS exemption documentation, factor that into the BOM review.

Frequently asked questions

Can MAX6429EHUR-T be used for a single cell Li-Po or lithium-ion battery?

Yes. The MAX6429EHUR-T is a multi-chemistry battery monitor for a single cell, so it works with Li-Po and Li-ion cells as well as NiMH, NiCd, and other chemistries. The single-cell rating means it monitors exactly one series cell.

What is the MAX6429EHUR-T used for?

It is a battery monitor IC that supervises the voltage of a single rechargeable cell. Typical applications include portable devices, battery packs, handheld instruments, and backup systems where a single Li-Po, Li-ion, or other chemistry cell needs over-discharge or under-voltage monitoring.
