MAX8672ETD+T

Overview

The MAX8672ETD+T is a battery monitor and fuel gauge IC designed for supervising lithium-ion battery packs. It integrates high-accuracy voltage, current, and temperature measurement capabilities to provide precise state-of-charge (SOC) and state-of-health (SOH) calculations. The device features a compact TDFN-14 package suitable for space-constrained portable applications.

Feature Summary

• Integrates high-precision analog front-end for simultaneous voltage, current, and temperature sensing
• Provides accurate state-of-charge and state-of-health estimation algorithms
• Supports single-cell lithium-ion battery pack supervision

Applications

• Portable electronic devices requiring precise battery monitoring
• Lithium-ion battery pack management systems
• Medical equipment with strict power management requirements

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official Analog Devices documentation. Ensure the component matches the exact TDFN-14 footprint requirements for your PCB design. Check for any obsolescence notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when precise coulomb counting and SOC accuracy are critical for lithium-ion applications. Consider the TDFN-14 package size constraints and thermal performance requirements. Evaluate the need for integrated temperature sensing versus external sensors based on system complexity. Compare against other Maxim Integrated fuel gauges if additional communication interfaces or multi-cell support are required.

Part Context

The MAX8672 belongs to Maxim Integrated's portfolio of battery management solutions. It complements other power management ICs by providing detailed battery health data rather than just charging control. This part fits into systems requiring reliable energy tracking for extended operational life and safety.

Replacement Considerations

Check for direct pin-to-pin replacements within the MAX8672 family. Verify functional compatibility with existing firmware if substituting with newer revisions. Consult official cross-reference lists for discontinued variants.
