MAX17211G+T0E

Overview

The MAX17211G+T0E is a ModelGauge m5 fuel gauge IC designed for single-cell lithium-ion battery monitoring. It operates within a battery voltage range of +2.1V to +4.9V and features a typical operating supply current of 18uA. The device is housed in a 14-TDFN (3x3mm) package and supports surface-mount installation. It functions across an extended temperature range from -40°C to +85°C, providing accurate state-of-charge data without requiring battery characterization.

Feature Summary

• Implements ModelGauge m5 algorithm for precise state-of-charge measurement
• Features non-volatile memory configuration for independent operation
• Includes integrated thermistor measurement network for real-time temperature monitoring

Applications

• Single-cell lithium-ion battery pack monitoring
• Portable electronic devices requiring accurate power management
• Battery-powered systems with limited space constraints

Procurement Notes

Verify the specific suffix 'T0E' against official Analog Devices documentation to confirm tape-and-reel specifications and moisture sensitivity level. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high accuracy without battery characterization. Consider the 14-TDFN package size for space-constrained designs. Verify that the system architecture supports the required serial interface communication for data retrieval.

Part Context

This part belongs to the MAX172xx series of fuel gauges, which are widely used in portable electronics. The MAX17211 specifically targets single-cell applications, offering a balance of accuracy and low power consumption compared to older generation models.

Replacement Considerations

Direct pin-compatible alternatives within the same family include the MAX17201 and MAX17215. Verify functional differences such as cell count support and specific algorithm updates when substituting.
