MAX17313G+T

Overview

The MAX17313G+T is a 24µA IQ standalone pack-side fuel gauge IC with protector and optional SHA-256 authentication for 1-cell lithium-ion/polymer batteries. It monitors voltage, current, temperature, and state of charge using the ModelGauge m5 algorithm. The device provides protection against over/undervoltage, overcurrent, short-circuit, and thermal conditions via external high-side N-FETs. It features a unique 64-bit ID and integrates SHA-256 authentication to prevent cloning.

Feature Summary

• Integrates ModelGauge m5 algorithm for accurate state-of-charge tracking
• Includes built-in protector functions for battery safety management
• Supports SHA-256 authentication with unique 64-bit ID for security

Applications

• Smartphones and tablets
• Wearable devices and smartwatches
• Medical devices and health monitors
• Digital cameras and handheld terminals

Procurement Notes

Verify the exact suffix matches 'G+T' for the specific package variant. Confirm that the required SHA-256 authentication feature is enabled in the configuration. Ensure compatibility with the target 1-cell Li-ion or Li-polymer battery chemistry. Check for availability of the evaluation kit if development support is needed.

Selection Notes

Select this component when high accuracy and security are required for single-cell battery packs. The ModelGauge m5 algorithm compensates for aging and temperature variations. Consider the external N-FET requirements for the protection circuitry. Evaluate the need for SHA-256 authentication based on anti-cloning requirements.

Part Context

This part belongs to the MAX17301–MAX17313 series of fuel gauges. It shares core functionality with other variants in the family but differs in package and specific authentication options. The series is designed for portable electronics requiring reliable power management.

Replacement Considerations

Check MAX17301 through MAX17313 variants for pin-compatible alternatives. Verify if the specific G+T package is available from authorized distributors. Ensure substitute parts support the same ModelGauge m5 algorithm and SHA-256 capabilities.
