MAX6431DHUS-T

Overview

The MAX6431DHUS-T is a battery monitor IC designed for multi-chemistry applications, supporting two-cell configurations. It operates within a temperature range of -40°C to 85°C and utilizes a SOT143-4 surface-mount package. This component serves as a dedicated solution for monitoring battery status in systems requiring reliable power management without complex interface protocols.

Feature Summary

• Designed for multi-chemistry battery monitoring
• Supports two-cell battery configurations
• Operates across extended industrial temperature ranges

Applications

• Grid power infrastructure
• Cell phone towers
• A/C power substations
• Internet infrastructure equipment

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation matches Analog Devices Inc. or Maxim Integrated legacy branding. Ensure the part number corresponds to the DHUS variant with the SOT143-4 package. Cross-reference datasheets for any recent obsolescence notices or lifecycle changes.

Selection Notes

Select this component for applications requiring simple, non-serial battery monitoring for two-cell stacks. It is suitable for environments where multi-chemistry compatibility is necessary. Consider the SOT143-4 footprint constraints during PCB layout. Verify that the absence of digital interfaces meets system design requirements.

Part Context

This device belongs to the MAX6431 family of battery monitors from Maxim Integrated, now part of Analog Devices. The family focuses on standalone monitoring solutions for portable and infrastructure power systems. The DHUS suffix denotes the specific package type and thermal characteristics.
