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/

● 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
