EVALUATION KIT AVAILABLE  
MAX17201/MAX17205/  
MAX17211/MAX17215  
Stand-Alone ModelGauge m5 Fuel Gauge  
with SHA-256 Authentication  
General Description  
Benefits and Features  
The MAX1720x/MAX1721x are ultra-low power stand-alone  
fuel gauge ICs that implement the Maxim ModelGauge™  
m5 algorithm without requiring host interaction for configura-  
tion. This feature makes the MAX1720x/MAX1721x excellent  
pack-side fuel gauges. The MAX17201/MAX17211 monitor a  
single cell pack. The MAX17205/MAX17215 monitor and bal-  
ance a 2S or 3S pack or monitor a multiple-series cell pack.  
● ModelGauge m5 Algorithm  
• Eliminates Error when Approaching Empty Voltage  
• Eliminates Coulomb-Counter Drift  
• Current, Temperature, and Age Compensated  
• Does Not Require Empty, Full, or Idle States  
• No Characterization Required for EZ Performance  
(See the ModelGauge m5 EZ Performance Section)  
• Cycle+ Age Forecasting Observes Lifespan  
To prevent battery pack cloning, the ICs integrate SHA-  
256 authentication with a 160-bit secret key. Each IC  
incorporates a unique 64-bit ID.  
● Nonvolatile Memory for Stand-Alone Operation  
• Learned Parameters and History Logging  
• Up to 75 Words Available for User Data  
The ModelGauge™ m5 algorithm combines the short-term  
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. The IC automatically compensates  
for cell aging, temperature, and discharge rate, and pro-  
vides accurate state of charge (SOC) in milliampere-hours  
(mAh) or percentage (%) over a wide range of operating  
conditions. As the battery approaches the critical region  
near empty, the ModelGauge m5 algorithm invokes a spe-  
cial error correction mechanism that eliminates any error.  
The ICs provide accurate estimation of time-to-empty and  
time-to-full, Cycle+™ age forecast, and three methods  
for reporting the age of the battery: reduction in capacity,  
increase in battery resistance, and cycle odometer.  
● Precision Measurement System  
• No Calibration Required  
● Time-to-Empty and Time-to-Full Estimation  
● Temperature Measurement  
• Die Temperature  
• Up to Two External Thermistors  
● Multiple Series Cell Pack Operation  
● Low Quiescent Current  
• MAX172x1: 18µA Active, 9µA Hibernate  
• MAX172x5: 25µA Active, 12µA Hibernate  
● Alert Indicator for Voltage, SOC, Temperature,  
Current, and 1% SOC Change  
● High-Speed Overcurrent Comparators  
● Predicts Remaining Capacity Under Theoretical Load  
● SHA-256 Authentication  
The ICs provide precision measurements of current, voltage,  
and temperature. Temperature of the battery pack is mea-  
sured using an internal temperature measurement and up to  
two external thermistors supported by ratiometric measure-

● Maxim 1-Wire or 2-Wire (I C) Interface  
®
ments on auxiliary inputs. A Maxim 1-Wire (MAX17211/  
2
● SBS 1.1 Compatible Register Set  
MAX17215) or 2-wire I C (MAX17201/MAX17205) inter-  
face provides access to data and control registers. The ICs  
are available in lead-free, 3mm x 3mm, 14-pin TDFN and  
1.6mm x 2.4mm 15-bump WLP packages.  
Applications  
● Smartphones and Tablets  
● Portable Game Players  
● e-Readers  
Ordering Information appears at end of data sheet.  
● Digital Still and Video Cameras  
● Handheld Computers and Terminals  
● Portable Medical Equipment  
● Handheld Radios
