DESCRIPTION

•

Requires No User Calibration

The bqJUNIOR series are highly accurate

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

pacity 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. Compen-

sations for battery temperature, self-discharge, and

discharge rate are applied to the capacity

measurments to provide available time-to-empty in-

formation across a wide range of operating con-

ditions. 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.

Programmable Input/Output Port

Internal User EEPROM Configuration Memory

Automatic Capacity Reduction With Age

Stable Oscillator Without External

Components

•

Dynamic End-of-Discharge Detection Delay to

Allow Use in a High-Dynamic Load

Environment

Automatic Sleep Mode When Communication

Lines are Low

•

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
