MAX17261METD+T

Overview

The MAX17261METD+T is a single-cell lithium-ion fuel gauge from the ModelGauge m5 EZ family, designed for portable devices. It operates within a supply voltage range of 4.9V and provides a 1.8V output. The device supports Lithium-ion and Lithium Iron Phosphate (LiFePO4) battery chemistries. It features a low operating supply current of 15uA and functions reliably across an extended temperature range from -40°C to +85°C. The component is housed in a compact TDFN-14 surface-mount package.

Feature Summary

• Implements ModelGauge m5 EZ algorithm for accurate state-of-charge estimation without requiring complex calibration procedures.
• Supports both single-cell and multi-cell battery pack configurations for flexible system design.
• Integrates internal self-discharge detection capabilities to maintain accuracy over varying usage patterns.

Applications

• Portable consumer electronics such as smartphones and tablets
• Medical devices requiring precise battery monitoring
• Industrial handheld equipment

Procurement Notes

Verify the specific suffix METD against official Analog Devices documentation to confirm pinout and thermal pad configuration. Ensure compatibility with the target PCB footprint and soldering profile. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement.

Selection Notes

Select this component when high accuracy is required for single-cell lithium-based batteries without external calibration. Consider the TDFN-14 package size constraints and the need for I2C interface connectivity. Evaluate if the integrated self-discharge detection meets the long-term storage requirements of the application.

Part Context

This part belongs to the MAX1726x series of fuel gauges, which utilize the ModelGauge m5 EZ technology. It serves as a standalone solution for battery management, offering improved accuracy over previous generations like the MAX17047. The series is widely used in applications demanding reliable power management in compact form factors.

Replacement Considerations

The MAX17260SETD+T is a documented alternative within the same family, featuring similar functionality but potentially different current sensing options. Verify pin-to-pin compatibility and software register mapping before substitution.
