MAX17201X+T

Overview

The MAX17201X+T is a ModelGauge m5 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 provides an output voltage of 1.8 V with a maximum output current of 50 mA. The device features a low operating supply current of 18 uA and functions across a temperature range of -40°C to +85°C. It utilizes an I2C interface and is housed in a compact 15-WLP package.

Feature Summary

• Implements ModelGauge m5 algorithm for accurate state-of-charge estimation
• Supports non-volatile memory configuration for independent operation
• Integrates thermistor measurement network for real-time temperature monitoring

Applications

• Single-cell lithium-ion battery management systems
• Portable electronic devices requiring precise fuel gauging
• IoT sensors and wearables with limited power budgets

Procurement Notes

Verify the specific suffix 'X' against the manufacturer's official datasheet to confirm pinout, thermal characteristics, and electrical tolerances match your design requirements. Ensure the WLP-15 package footprint aligns with your PCB layout constraints. Cross-reference the RoHS status and environmental compliance data provided in the latest component documentation before finalizing procurement.

Selection Notes

Select this component when designing for single-cell applications where high accuracy and low quiescent current are critical. The ModelGauge m5 technology offers superior performance compared to traditional coulomb counting methods. Consider the 15-WLP package size if board space is constrained. Verify that the I2C interface compatibility matches your system controller.
