MAX6431CHUS

Overview

The MAX6431CHUS is a multi-chemistry battery monitor IC designed for monitoring dual-cell battery systems. It tracks battery status and provides fault protection for single Li-ion or multi-cell alkaline, NiMH, and NiCd power sources. The device features a dual-output architecture and is factory-trimmed for accuracy. It is available in surface-mount packages including SOT-23-4, TO-253-4, and TO-253AA.

Feature Summary

• Multi-chemistry support for various battery types
• Dual-output configuration for system flexibility
• Factory-trimmed precision for reliable monitoring

Applications

• Dual-cell battery system monitoring
• Single Li-ion battery management
• Alkaline, NiMH, and NiCd power source tracking

Procurement Notes

Verify the specific suffix (e.g., +T) to confirm tape-and-reel packaging if required. Confirm product status as obsolete before finalizing design-in decisions. Ensure package type matches the target PCB footprint. Cross-reference datasheet revisions for any updated electrical characteristics or pinout definitions prior to procurement.

Selection Notes

Select this component when monitoring dual-cell configurations with mixed chemistries is required. Consider the available surface-mount packages for space-constrained designs. Evaluate the factory-trimmed accuracy against application tolerance requirements. Verify compatibility with existing fault protection circuitry in the system design.

Part Context

This part belongs to the Maxim Integrated battery management portfolio. It serves as a specialized monitor for multi-cell setups rather than a general-purpose voltage regulator. The device integrates monitoring functions to ensure safe operation of diverse battery technologies within compact electronic devices.
