MAX17312G+T

Overview

The MAX17312G+T is a single-cell Lithium-Ion and Lithium-Polymer battery fuel gauge IC from the GaugeM5 family. It operates within a supply voltage range of up to 4.9V and supports a 1-Wire interface for communication. The device is housed in a compact 14-pin TDFN package with an exposed pad, measuring 3x3 mm. It functions across an operating temperature range starting from -40°C. This component provides accurate state-of-charge monitoring for portable electronics requiring precise battery management.

Feature Summary

• Provides accurate state-of-charge monitoring for single-cell lithium-based batteries
• Utilizes a 1-Wire interface for simplified system integration
• Designed for compact portable applications with small form factor packaging

Applications

• Smartphones and mobile phones
• Tablets and handheld computers
• Portable medical devices

Procurement Notes

Verify the specific suffix 'G' indicates lead-free compliance and 'T' denotes tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc., which acquired Maxim Integrated. Ensure the datasheet matches the exact part number to avoid confusion with similar GaugeM5 variants that may have different calibration or pinout requirements.

Selection Notes

Select this component for applications requiring high accuracy in state-of-charge estimation for single-cell Li-Ion or Li-Po batteries. Consider the 1-Wire interface if minimizing pin count is critical. Evaluate the thermal performance of the TDFN package against the expected power dissipation in the target enclosure design.

Part Context

This part belongs to the GaugeM5 family of fuel gauges, designed for consumer electronics. Analog Devices Inc. continues the Maxim Integrated product line. The MAX17312 variant specifically targets single-cell applications, distinguishing it from multi-cell solutions in the broader portfolio.

Replacement Considerations

Check for direct cross-reference part numbers within the GaugeM5 family. Verify compatibility of the 1-Wire protocol and physical footprint before substituting.
