MAX6432DHUS-T

Overview

The MAX6432DHUS-T is a battery monitoring integrated circuit designed for multi-chemistry applications. It supports two-cell configurations and operates within a supply voltage range of 1.6V to 5.5V. The device is housed in an SOT-23-4 package, also identified as TO-253-4 or SOT143-4. It functions effectively across an operating temperature range of -40°C to +85°C (TA). This component serves as a specialized power management solution for tracking battery status in portable electronic devices.

Feature Summary

• Supports multi-chemistry battery types for versatile application compatibility
• Enables monitoring of dual-cell battery configurations
• Operates with low supply voltage requirements starting at 1.6V

Applications

• Portable electronic devices requiring battery status tracking
• Multi-chemistry battery management systems
• Dual-cell battery powered equipment

Procurement Notes

Verify the exact package designation, as sources list SOT-23-4, SOT143-4, and TO-253-4. Confirm part status, as some listings indicate obsolescence while others show availability from secondary distributors. Ensure the suffix matches the required reel configuration if applicable. Cross-reference the manufacturer number with Analog Devices or Maxim Integrated documentation to confirm current manufacturing status and lead times.

Selection Notes

Select this component when multi-chemistry support and dual-cell monitoring are required. The low minimum supply voltage of 1.6V makes it suitable for deeply discharged battery states. Verify that the SOT-23-4 footprint fits the design constraints. Consider the operating temperature range of -40°C to +85°C for environmental suitability. Check for obsolete status before finalizing the bill of materials.

Part Context

This part belongs to the MAX6432 series of battery monitors. It is manufactured by Analog Devices Inc./Maxim Integrated. The series focuses on battery health and status monitoring for portable applications. The specific model DHUS-T indicates the package type and tape-and-reel packaging format. It is distinct from supervisor ICs like the MAX6855, focusing instead on battery chemistry and cell count.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Users should consult official Analog Devices or Maxim Integrated documentation for direct replacements or pin-compatible alternatives.
