MAX17205G+T

Overview

The MAX17205G+T is a ModelGauge m5 fuel gauge IC designed for lithium-ion and lithium-polymer batteries. It operates within a supply voltage range of 4.2 V to 20 V, with an output voltage of 3.4 V and output current capability of 50 mA. The device features a low operating supply current of 25 uA and functions reliably across a temperature range of -40 C to +85 C. Packaged in a WLP-15 format for surface mount installation, it provides precise battery monitoring solutions.

Feature Summary

• Implements ModelGauge m5 algorithm for accurate state-of-charge estimation
• Supports both lithium-ion and lithium-polymer battery chemistries
• Provides I2C interface connectivity for system integration

Applications

• Smart sensor networks requiring long-term battery life
• Internet of Things (IoT) devices with infrequent charging cycles
• Portable consumer electronics utilizing single-cell lithium batteries

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm that the component meets RoHS compliance standards required by your manufacturing process. Ensure compatibility with the WLP-15 footprint during PCB layout finalization. Cross-reference the manufacturer's latest documentation for any updates regarding lead-free specifications or material declarations before placing orders.

Selection Notes

Select this component when high accuracy is required for non-rechargeable or primary battery applications where voltage lookup methods are insufficient. Consider the low quiescent current of 25 uA for power-sensitive designs. Evaluate the WLP-15 package size against available board space constraints. Verify that the operating temperature range aligns with the environmental conditions of the target application.

Part Context

This part belongs to the MAX17205 series of fuel gauges from Analog Devices/Maxim Integrated. It utilizes the ModelGauge m5 technology to deliver precise battery management capabilities. The series is engineered for applications demanding reliable state-of-charge data without complex calibration procedures, distinguishing it from basic voltage-based monitoring solutions.

Replacement Considerations

The MAX17205X+T is listed as a related variant within the same product family. Verify pinout and functional equivalence before substitution. Consult official replacement guides for any changes in package dimensions or electrical characteristics.
