The MAX17262HEWL+T is an ultra-low-power fuel-gauge integrated circuit (IC) designed by Analog Devices (formerly Maxim Integrated) for single-cell lithium-ion (Li-ion) batteries, offering precision monitoring and extended battery life for portable applications.

• ModelGauge m5 EZ Algorithm: Combines high short-term accuracy of coulomb counting with long-term stability of voltage-based estimation, featuring automatic temperature compensation for industry-leading precision.
• Internal Current Sensing: Integrates low-resistance current sensor, eliminating need for external sense resistors and supporting pulse currents up to 3.1A.
• Precision Monitoring: Accurately measures battery voltage, current, and temperature via internal sensor or external thermistor.
• State-of-Charge & Capacity Reporting: Provides precise SOC (%) and remaining capacity (mAh) estimates for batteries ranging from 100mAh to 6Ah.
• Adaptive Compensation: Automatically compensates for battery aging, temperature fluctuations, and varying discharge rates.
• Error Correction: Activates special correction algorithms as battery nears empty to minimize SOC errors.
• Battery Health Tracking: Monitors and reports battery health through capacity degradation, increased internal resistance, and cycle count.
• Ultra-Low Power Consumption: Operates on mere 5.2 µA quiescent current, maximizing battery life in portable devices.
• I²C Interface: Communicates battery data to host system via standard 2-wire interface.

• Wearable Devices: Smart watches, fitness bands, and hearables
• Wireless Audio: Bluetooth headsets and true wireless stereo (TWS) earbud charging cases
• Healthcare & Medical: Portable medical devices, health monitors, and diagnostic equipment
• Portable Electronics: Handheld computers, point-of-sale (POS) terminals, and remote controls
• IoT & Smart Home: Wireless sensors, home automation modules, and battery-powered smart devices
• Consumer Products: Toys, portable speakers, and other compact, battery-operated devices
