MAX17311X+T

Overview

The MAX17311X+T is a ModelGauge M5 battery fuel gauge IC designed for single-cell lithium-ion and lithium-polymer batteries. It provides precise state-of-charge monitoring using advanced algorithmic modeling rather than simple voltage measurement. The device integrates fault protection features including over-current, over-temperature, over-voltage, and short-circuit detection to ensure safe operation. Communication with the host system occurs via an I²C interface. The component is housed in a compact 15-wafer-level package (WLP) measuring 1.68x2.45 mm, suitable for space-constrained portable electronics.

Feature Summary

• Implements ModelGauge M5 technology for accurate charge depletion detection without requiring calibration
• Integrates comprehensive hardware fault protection mechanisms for enhanced battery safety
• Utilizes a minimal footprint wafer-level package for dense board layouts

Applications

• Portable consumer electronics such as smartphones and tablets
• Industrial equipment requiring reliable power management
• Automotive infotainment and control modules
• Aerospace avionics systems

Procurement Notes

Verify the specific suffix 'X' against the manufacturer's official datasheet to confirm pinout and functional variations. Ensure the ordering part number matches the exact package type and temperature grade required for your design. Cross-reference the revision level with the latest Analog Devices documentation to avoid discrepancies in electrical characteristics or recommended operating conditions.

Selection Notes

Select this component when high accuracy in state-of-charge estimation is critical for single-cell lithium-based chemistries. It is appropriate for designs where board space is limited due to its small WLP form factor. Consider the I²C interface compatibility with your microcontroller and verify that the integrated fault protections meet the safety requirements of the target application environment.
