MAX6432EHUS

Overview

The MAX6432EHUS is a dual-output, factory-trimmed battery monitor IC designed for single Li+ or multi-cell alkaline/NiMH/NiCd power supplies. It provides overcharge protection and undervoltage detection with high precision voltage measurement. The device operates within a temperature range of -40°C to +85°C and features two independent monitoring channels. Packaged in a SOT-143-4 outline, it supports multi-chemistry applications and includes fault protection mechanisms suitable for embedded control systems requiring reliable battery management.

Feature Summary

• Dual-output architecture supporting single lithium-ion or multi-cell alkaline, NiMH, and NiCd batteries
• Factory-trimmed precision for accurate voltage measurement and monitoring
• Integrated overcharge protection and undervoltage detection capabilities
• Operates across an extended industrial temperature range

Applications

• Embedded control applications
• Single Li+ battery powered devices
• Multi-cell alkaline power supply systems
• NiMH and NiCd battery management circuits

Procurement Notes

Verify the specific suffix (e.g., +T) against your bill of materials to ensure correct packaging and tape-and-reel availability. Confirm that the SOT-143-4 package matches your PCB footprint requirements. Ensure the component status is active for long-term supply continuity. Cross-reference the manufacturer designation between Maxim Integrated and Analog Devices Inc. as both entities are associated with this part number lineage.

Selection Notes

Select this component when dual-channel monitoring is required for diverse battery chemistries including lithium-ion, alkaline, and nickel-based cells. The factory-trimmed nature reduces calibration needs compared to untrimmed alternatives. Consider the SOT-143-4 package constraints for space-limited designs. Verify that the operating temperature range meets the environmental conditions of the target application.

Part Context

This component belongs to the battery management category under supervisor and reset ICs. It is manufactured by Analog Devices Inc./Maxim Integrated. The part serves as a specialized monitor for maintaining battery health and preventing damage through precise voltage threshold detection. It is distinct from general-purpose voltage supervisors due to its multi-chemistry support and dual-output configuration.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official distributor databases for direct replacements. Ensure any alternative maintains the SOT-143-4 package and dual-output functionality.
