MAX17211G+

Overview

The MAX17211G+ is a ModelGauge m5 EZ fuel gauge IC designed for single-cell lithium-ion and lithium-polymer batteries. It operates within a battery voltage range of +2.1V to +4.9V and features a supply current of 18 uA. The component is housed in a 14-TDFN (3x3) package with surface-mount installation. It supports an operating temperature range from -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Implements ModelGauge m5 EZ algorithm for accurate state-of-charge monitoring without battery characterization
• Utilizes non-volatile memory configuration for independent operation
• Includes thermistor measurement network for real-time temperature monitoring

Applications

• Single-cell lithium-ion battery pack management
• Lithium-polymer battery fuel gauging
• Portable electronic device power management

Procurement Notes

Verify the specific suffix 'G+' against the manufacturer's official documentation to confirm lead-free status and compliance with RoHS3 regulations.
