•

Reports Temperature, Voltage, and Current

High Accuracy Charge and Discharge Current

Integration with Automatic Offset Calibration

DESCRIPTION

•

Requires No User Calibration

The bqJUNIOR™ series are highly accurate

stand-alone single-cell Li-Ion and Li-Pol battery

capacity monitoring and reporting devices targeted at

space-limited, portable applications. The IC monitors

a voltage drop across a small current sense resistor

connected in series with the battery to determine

charge and discharge activity of the battery.

Programmable Input/Output Port

Internal User EEPROM Configuration Memory

Automatic Capacity Reduction With Age

Stable Oscillator Without External

Components

Compensations

self-discharge, and discharge rate are applied to the

capacity measurments to provide available

Dynamic End-of-Discharge Detection Delay to

Allow Use in a High-Dynamic Load

Environment

time-to-empty information across a wide range of

operating conditions. Battery capacity is automatically

recalibrated, or learned, in the course of a discharge

cycle from full to empty. Internal registers include

current, capacity, time-to-empty, state-of-charge, cell

temperature and voltage, status, and more.

•

Automatic Sleep Mode When Communication

Lines are Low

Available in a Small 3 mm x 4 mm QFN

Package

Five Low-Power Operating Modes

– Active: < 90 µA

The bqJUNIOR can operate directly from single-cell

Li-Ion and Li-Pol batteries and communicates to the

system over a HDQ one-wire or I²C serial interface.

– Sleep: < 2.5 µA

– Ship: < 2 µA (bq27000 only)

– Hibernate: < 1.5 µA

– Data Retention: < 20 nA
