MAX6432DHUS

Overview

The MAX6432DHUS is a battery monitor IC designed for multi-chemistry applications, specifically supporting two-cell configurations. It operates within a temperature range of -40°C to 85°C and utilizes a SOT143-4 surface-mount package. The device provides low-battery voltage alarm outputs when supply voltage drops below specified thresholds and resets when voltage rises above high-level gate limits. It features a moisture sensitivity level of 3, ensuring a 168-hour shelf life under specified conditions.

Feature Summary

• Designed strictly for monitoring two-cell battery packs without stackable interfaces or level-shifting capabilities
• Suitable for single lithium-ion cells or multiple alkaline/NiCd/NiMH battery systems
• Generates low-battery voltage alarm outputs upon detecting voltage drops below defined minimums

Applications

• Monitoring single lithium-ion (Li+) battery systems
• Managing multiple alkaline battery powered devices
• Supervising NiCd or NiMH battery pack voltages

Procurement Notes

Verify the specific suffix (e.g., DHUS vs. DHUS-T) against official Analog Devices documentation to confirm tape-and-reel versus bulk packaging status. Ensure the component matches the exact part number for the required operating temperature range and package type. Cross-reference datasheets to confirm moisture sensitivity level and pinout compatibility before integration into designs.

Selection Notes

Select this component only for applications requiring precise monitoring of two-cell battery packs. Note that it lacks stackable interfaces or level-shifting capabilities necessary for series-connected multi-cell stacks beyond two cells. It is suitable for multi-chemistry batteries including Li+, alkaline, NiCd, and NiMH types where simple voltage threshold detection is sufficient.

Part Context

The MAX6432 is part of a family of low-power battery monitors featuring hysteresis. The DHUS variant specifically denotes a two-cell configuration in a small outline transistor package. This model serves as a cost-effective solution for basic battery supervision tasks in portable electronics where complex fuel gauging is not required.

Replacement Considerations
