Overview

The Maxim Integrated MAX17262REWL+ is an ultra-low power fuel-gauge IC which implements the Maxim ModelGauge™ m5 algorithm. The IC monitors a single-cell battery pack and supports internal current sensing for up to 3.1 A pulse current. The IC provides the best performance for batteries with 100 mAhr to 6 Ahr capacity.The MAX17263 is an ultra-low power fuel-gauge IC which implements the Maxim ModelGauge m5 algorithm. The IC monitors either a single cell battery pack or multiple-series cell battery pack with an external resistor divider. The IC drives 3 to 12 automatically-counted LEDs to indicate battery state-of-charge on a push-button press, or any other system status using I²C commands. The IC is available in a 3 mm x 3 mm 14-pin TDFN package.The ModelGauge m5 EZ makes fuel-gauge implementation easy by eliminating battery characterization requirements and simplifying host software interaction. Its robust algorithm provides tolerance against battery diversity for most lithium batteries and applications.Features: ModelGauge m5 EZ No characterization required for EZ performance, Robust against battery variation, Eliminates error near empty voltage, Eliminates coulomb-counter drift, Compensates for age, current, temperature, Does not require empty, full, or idle states, Supports Li+ and variants including LiFePO4, Thermistor or ±1°C internal temperature, Dynamic power estimates power capability during discharge, Time-to-empty and time-to-full estimation, Predicts remaining capacity under theoretical load, No calibration required, Alert indicator for voltage, SOC, temperature, current, and 1% SOC change, Wearables and smartwatches, Bluetooth headset cases, Health and fitness monitors, Handheld computers and terminals, Wireless speakers, Medical devices, Drones, Power tools, E-bikes, Headlamps and torches, Battery backup, Toys, Home and building automation, sensors
