MAX17320G10+T

Overview

The MAX17320G10+T is a standalone battery pack-side fuel gauge IC designed for 2 to 4 series-connected lithium-ion or polymer cells. It features ModelGauge m5 technology for accurate state-of-charge monitoring and includes an integrated protection device. The component operates with a quiescent current of 38µA and supports optional SHA-256 authentication. Packaged in a 24-TQFN (4x4) footprint, it enables precise battery management in space-constrained applications.

Feature Summary

• Integrates ModelGauge m5 algorithm for high-accuracy fuel gauging
• Includes built-in protection device for enhanced safety
• Supports optional SHA-256 authentication for secure communication
• Detects internal battery self-discharge conditions

Applications

• Industrial equipment
• Automotive systems
• Aerospace electronics

Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required authentication protocols if SHA-256 functionality is needed. Cross-reference datasheet revisions to validate pinout and electrical characteristics before integration into design.

Selection Notes

Select this component when requiring a compact, low-power fuel gauge for multi-cell lithium batteries. The integrated protection simplifies bill of materials by reducing external components. Consider the 24-TQFN package size for PCB layout constraints. Verify that the 38µA quiescent current meets system standby requirements.

Part Context

This part belongs to the MAX17320 family of battery management solutions from Maxim Integrated, now part of Analog Devices. The G10 suffix typically denotes specific packaging or temperature grade variations within the standard MAX17320 product line. It serves as a direct replacement for previous generation fuel gauges requiring similar cell count support and accuracy levels.

Replacement Considerations

Check for MAX17320G10+ without the 'T' suffix if bulk packaging is preferred instead of tape-and-reel. Verify cross-compatibility with MAX17321 or MAX17322 if single-cell or different cell count configurations are required. Confirm pin-to-pin compatibility with existing designs using older fuel gauge variants.
