MAX17260BEWL+T

Overview

The MAX17260BEWL+T is a single-cell fuel gauge from the ModelGauge m5 EZ family, designed for lithium-ion and LiFePO4 batteries. It operates on a supply voltage of 2.3 V to 4.9 V with a typical quiescent current of 15 µA. The device provides accurate state-of-charge monitoring via an I²C interface and supports optional high-side current sensing. It is housed in a compact 14-pin TDFN (3x3 mm) package with an exposed pad, suitable for surface-mount assembly.

Feature Summary

• Implements ModelGauge m5 EZ algorithm for precise battery state-of-charge estimation without requiring complex calibration.
• Supports both low-side and optional high-side current sensing configurations for flexible system design.
• Features ultra-low operating current consumption to maximize battery runtime in portable applications.

Applications

• Portable electronic devices requiring accurate battery life prediction
• Smartphones and tablets utilizing lithium-ion or LiFePO4 cells
• Wearable health and fitness monitors
• Medical handheld instruments

Procurement Notes

Verify the specific suffix 'BEWL' against the manufacturer's official datasheet to confirm pinout and package compatibility. Ensure the component meets RoHS standards as indicated in public documentation. Cross-reference the ordering part number with Analog Devices Inc. to avoid counterfeit risks and confirm availability status through authorized channels.

Selection Notes

Select this component when high accuracy is required for single-cell lithium-based batteries without extensive calibration overhead. The ModelGauge m5 EZ technology simplifies implementation compared to older generations. Consider the 14-TDFN package size constraints and ensure the PCB layout supports the exposed thermal pad for optimal performance and reliability.

Part Context

This part belongs to the MAX17260 series within the Maxim Integrated portfolio, now part of Analog Devices Inc. It is part of the ModelGauge line, which focuses on advanced fuel gauging solutions. The BEWL suffix typically denotes a specific tape-and-reel packaging variant of the standard MAX17260SETD+T device.

Replacement Considerations

The MAX17260SETD+T is a direct functional equivalent within the same series. Verify that the package type (TDFN vs. WLP) matches the target PCB footprint, as the BEWL suffix may indicate a different physical package than the SETD variant.
