MAX17301–MAX17303/

MAX17311–MAX17313

1-Cell ModelGauge m5 EZ Fuel Gauge with

Protector and SHA-256 Authentication

General Description

Benefits and Features

The MAX17301–MAX17303/MAX17311–MAX17313 is a

● Battery Health + Programmable Safety/Protection

• Overvoltage (Temperature Dependent)

• Overcharge Current

24μA I stand-alone pack-side fuel gauge IC with protec-

tor and optional SHA-256 authentication for 1-cell lithium-

ion/polymer batteries.

• Over/Undertemperature

• Ideal Diode Discharge During Charge Fault

• Charging Prescriptions (JEITA)

• Zero-Volt Charging Option

• Undervoltage + SmartEmpty

• Overdischarge/Short-Circuit

The IC monitors the voltage, current, temperature, and

state of the battery to provide against over/undervoltage,

overcurrent, short-circuit, over/undertemperature and

overcharge conditions protection using external high-side

N-FETs, and provides charging prescription to ensure that

the lithium-ion/polymer battery operates under safe condi-

tions prolonging the life of the battery.

● Nonvolatile Memory for Stand-Alone Operation

• History Logging, User Data (122 Bytes)

To prevent battery pack cloning, the IC integrates

SHA-256 authentication with a 160-bit secret key. Each IC

incorporates a unique 64-bit ID.

● Low Quiescent Current

• FETs Enabled: 24µA Active, 18µA Hibernate

• FETs Disabled: 7µA Ship, 0.5µA DeepShip,

0.1µA UV-Shutdown

The fuel gauge uses ModelGauge m5 algorithm that com-

bines the short-term accuracy and linearity of a coulomb

counter with the long-term stability of a voltage-based fuel

gauge to provide industry-leading fuel-gauge accuracy.

● Pushbutton Wakeup—Eliminates System

Consumption Until Button Press

● ModelGauge m5 EZ Algorithm

• Percent, Capacity,Time-to-Empty/Full, Age

• Cycle+™ Age Forecast

The IC automatically compensates for cell aging, temper-

ature, and discharge rate, and provides accurate state-of-

charge (SOC) in milliampere-hours (mAh) or percentage

(%) over a wide range of operating conditions.

● Dynamic Power—Estimates Power Capability

● Precision Measurement Without Calibration

• Current, Voltage, Power, Time, Cycles

• Die Temperature/Thermistor

Dynamic power functionality provides the instantaneous

maximum battery output power which can be delivered

to the system without violating the minimum system input

voltage.

Ordering Information appears at end of datasheet.

A Maxim 1-Wire or 2-wire I C interface provides access

to data and control registers. The IC is available in a

lead-free, 3mm x 3mm 14-pin TDFN and 1.7mm x 2.5mm

15-bump 0.5mm pitch WLP packages.
