MAX17211X+T0E

Overview

The MAX17211X+T0E is a ModelGauge m5 EZ fuel gauge IC designed for single-cell lithium-ion battery monitoring. It operates within a supply voltage range of 2.3 V to 4.9 V and delivers an output voltage of 1.8 V with a maximum output current of 50 mA. The device functions at a quiescent supply current of 18 uA and supports an operating temperature range from -40 C to +85 C. It utilizes a WLP-15 package for surface mount installation.

Feature Summary

• Implements ModelGauge m5 EZ algorithm for accurate state-of-charge estimation without requiring battery characterization.
• Provides digital fuel gauge data via I2C interface for system integration.
• Supports single-cell lithium-ion battery management applications.

Applications

• Single-cell lithium-ion battery monitoring in portable electronics
• Power management systems requiring accurate state-of-charge tracking
• Embedded devices utilizing ModelGauge technology

Procurement Notes

Verify the specific suffix T0E indicates the WLP-15 packaging configuration as documented. Confirm compatibility with the intended host controller interface requirements. Ensure environmental specifications meet the operational temperature constraints defined in the datasheet. Cross-reference the manufacturer part number with official Analog Devices documentation to validate component authenticity and revision status before procurement.

Selection Notes

Select this component when a compact solution for single-cell lithium-ion battery monitoring is required. The WLP-15 package offers a small footprint suitable for space-constrained designs. Consider the 18 uA quiescent current for low-power applications. Verify that the I2C interface aligns with the system's communication architecture and that the operating voltage range matches the target power supply rails.
