MAX17041G+T

Overview

The MAX17041G+T is a compact, low-cost host-side fuel gauge system designed for dual-cell (2S) lithium-ion battery packs. It operates with a 2.5V to 4.5V supply and features an I2C interface. The device provides precision voltage measurement with ±30mV accuracy up to 10.00V. It utilizes the ModelGauge algorithm for accurate relative state-of-charge calculation without requiring a sense resistor or full-to-empty relearning. The component is housed in an 8-pin TDFN package measuring 2mm x 3mm.

Feature Summary

• Supports host-side or battery-side fuel gauging for 2S lithium-ion configurations
• Delivers precise voltage measurement with specified accuracy limits
• Calculates relative capacity using the ModelGauge algorithm
• Eliminates the need for a current sense resistor

Applications

• Smartphones and tablets
• Health and fitness monitors
• Medical devices
• Digital still, video, and action cameras
• Handheld computers and terminals

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance and REACH status prior to integration. Ensure the specific suffix matches design requirements. Validate supply chain sources against manufacturer lists to avoid counterfeit components during procurement.

Selection Notes

Select this model specifically for dual-cell lithium-ion applications requiring high precision voltage monitoring. The absence of a sense resistor requirement simplifies board layout compared to other fuel gauge solutions. Consider the 2mm x 3mm TDFN package constraints for space-limited portable designs.

Part Context

This component belongs to the MAX1704x series of fuel gauges, which includes variants for single-cell configurations like the MAX17040. The series is characterized by ultra-compact packaging and low power consumption suitable for handheld equipment. It represents a cost-effective solution within the Analog Devices portfolio for portable electronics.

Replacement Considerations

The MAX17040G+T serves as a functional substitute for single-cell applications but differs in cell configuration. Verify compatibility regarding voltage range and package dimensions when considering alternative models from the same family.
