MAX17320X12+T

Overview

The MAX17320X12+T is a stand-alone pack-side fuel gauge IC with integrated protector, designed for 2S to 4S lithium-ion or lithium-polymer battery packs. It utilizes the ModelGauge m5 EZ algorithm to provide accurate state-of-charge and remaining capacity readings. The device features a low quiescent current of 38μA, ensuring minimal power drain during standby. It operates within a temperature range of -40°C to +85°C and is available in a 30-WLP package.

Feature Summary

• Integrates ModelGauge m5 EZ fuel gauge algorithm with built-in protection circuitry
• Provides high-accuracy state-of-charge monitoring for multi-cell battery packs
• Optimized for low-power operation with ultra-low quiescent current consumption

Applications

• Industrial equipment battery management
• Automotive subsystems requiring reliable pack monitoring
• Aerospace electronics with strict power constraints

Procurement Notes

Verify the specific suffix X12 against the official Analog Devices datasheet to confirm pinout and configuration compatibility. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Check for RoHS compliance markings on the packaging documentation.

Selection Notes

Select this part when a compact, standalone solution is required for 2S to 4S lithium-based battery systems. It is suitable for applications demanding high accuracy without complex external calibration. Consider the WLP package size if board space is limited compared to traditional QFN options.

Part Context

This component belongs to the ModelGauge series by Maxim Integrated, now part of Analog Devices. It represents an evolution in fuel gauge technology, combining measurement and protection in a single small footprint. The series targets portable and industrial devices where battery life prediction is critical.

Replacement Considerations

Check for direct cross-references such as MAX17320X10+T for similar functionality with potential pinout differences. Verify that any substitute maintains the same cell count support and algorithm version to ensure system compatibility.
