MAX6433UK/GH9-T

Overview

The MAX6433UK/GH9-T is a battery monitor integrated circuit designed for multi-chemistry applications, including Lithium-ion, Nickel Cadmium (NiCd), and Nickel Metal Hydride (NiMH) batteries. Manufactured by Analog Devices Inc./Maxim Integrated, this component functions as a power supply support circuit within the Battery Management product category. It is housed in a compact SOT-23-5 surface-mount package, facilitating integration into portable electronic devices requiring precise battery state monitoring.

Feature Summary

• Supports monitoring of multiple battery chemistries including Li-ion, NiCd, and NiMH
• Integrated battery protection and management functionality
• Compact SOT-23-5 surface-mount package design

Applications

• Lithium-ion battery pack monitoring systems
• Nickel-based rechargeable battery management circuits
• Portable electronic device power supply support

Procurement Notes

Verify the specific suffix (GH9-T) against official Analog Devices documentation to confirm exact tape-and-reel specifications and RoHS compliance status. Ensure the source document explicitly identifies the manufacturer as Analog Devices Inc. or Maxim Integrated. Cross-reference the part number with authorized distributors to confirm availability of the correct variant, as suffixes may indicate packaging or temperature grade differences not detailed in general summaries.

Selection Notes

Select this component when designing systems requiring multi-chemistry battery support in a minimal footprint. The SOT-23-5 package is suitable for space-constrained portable applications. Confirm compatibility with the specific battery chemistry (Li-ion, NiCd, or NiMH) intended for the target application, as the IC supports multiple types but requires appropriate external configuration.

Part Context

This part belongs to the MAX6433 family of battery monitor ICs from Maxim Integrated, now part of Analog Devices. These components are engineered for robust battery management in consumer electronics. The UK/GH9 designation typically refers to the specific package type and reel configuration, distinguishing it from other variants in the same functional family.

Replacement Considerations

Consult official Analog Devices substitution guides for verified equivalents. Generic replacements may not support the full range of multi-chemistry configurations or the specific SOT-23-5 pinout. Verify electrical characteristics and package dimensions before swapping.
