MAX17263

Single/Multi-Cell Fuel Gauge with ModelGauge

m5 EZ and Integrated LED Control

General Description

Benefits and Features

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-se-

ries 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 oth-

● 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, and Temperature

• Does Not Require Empty, Full, or Idle States

er system status using I C commands.

The ModelGauge m5 EZ algorithm makes fuel gauge im-

plementation easy by eliminating battery characterization

requirements and simplifying host software interac-

tion. The algorithm provides tolerance against battery di-

versity for most lithium batteries and applications.

● Monitors Single-Cell or Multiple-Cell Battery Packs

● Integrated LED Control with Push-Button Input

• Drives 3 to 12 LEDs, Automatically Counted

● Custom Pattern LED Control Using I C Commands

● Accurate Current Sensing

The algorithm combines the short-term accuracy and lin-

earity of a coulomb counter with the long-term stability of

a voltage-based fuel gauge, along with temperature com-

pensation to provide industry-leading fuel-gauge accura-

cy. The IC automatically compensates for cell-aging, tem-

perature, and discharge rate, and provides accurate state-

of-charge (SOC) in percentage (%) and remaining capac-

ity in milliampere-hours (mAh) over a wide range of oper-

ating conditions. As the battery approaches the critical re-

gion near empty, the algorithm invokes a special correc-

tion mechanism that eliminates any error. The IC provides

accurate estimation of time-to-empty and time-to-full and

provides three methods for reporting the age of the bat-

tery: reduction in capacity, increase in battery resistance,

and cycle odometer.

• High-Side or Low-Side Sensing Options

● Wide Sense Resistor Range: 1mΩ to 1000mΩ

● PCB Metal Sensing + Temperature Compensation

● Supports Li+ and Variants Including LiFePO

● 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

Ordering Information appears at end of data sheet.

The IC provides precision measurements of current, volt-

age, and temperature. The temperature of the battery

pack is measured using an internal temperature sensor or
