Product Overview

MAX17262REWL+T is a MAX17262 ultra-low power fuel-gauge IC which implements the ModelGauge™ m5 algorithm. The IC monitors a single-cell battery pack and supports internal current sensing. The IC provides best performance for batteries with 30mAhr to 6Ahr capacity. The ModelGauge m5 EZ makes fuel-gauge implementation easy by eliminating battery characterization requirements and simplifying host software interaction. The ModelGauge m5 EZ robust algorithm provides tolerance against battery diversity for most lithium batteries and applications. The ModelGauge m5 EZ algorithm combines the shortterm accuracy and linearity of a coulomb counter with the long-term stability of a voltage-based fuel gauge, along with temperature compensation to provide industry-leading fuel-gauge accuracy. Typical applications are wearables and smartwatches, Bluetooth headset cases, health and fitness monitors, medical devices, handheld computers and terminals, home and building automation, sensors, toys.
  • No characterization required for EZ performance, robust against battery variation
  • Eliminates error near empty voltage, eliminates coulomb-counter drift
  • Compensates for age, current, and temperature, does not require empty, full, or idle states
  • Low 5.2μA operating current, single-cell, internal 7mohm sensing
  • 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, constant power or constant current
  • Predicts remaining capacity under theoretical load, no calibration required
  • Temperature range from -40°C to +85°C, 9-WLP pin-package
