SLUSA91A –OCTOBER 2010–REVISED JANUARY 2012

2-Series, 3-Series, and 4-Series Li-Ion Battery Pack Manager

Check for Samples: bq3055

FEATURES

APPLICATIONS

•

Fully Integrated 2-Series, 3-Series, and

4-Series Li-Ion or Li-Polymer Cell Battery Pack

Manager and Protection

•

Notebook/Netbook PCs

Medical and Test Equipment

Portable Instrumentation

•

Advanced Compensated End-of-Discharge

Voltage (CEDV) Gauging

DESCRIPTION

•

High Side N-CH Protection FET Drive

Integrated Cell Balancing

Low Power Modes

The bq3055 device is a fully integrated, single-chip,

pack-based solution that provides a rich array of

features for gas gauging, protection, and

authentication for 2-series, 3-series, and 4-series cell

Li-Ion and Li-Polymer battery packs.

–

Low Power: < 180 µA

Sleep < 76 µA

Using its integrated high-performance analog

peripherals, the bq3055 device measures and

maintains an accurate record of available capacity,

voltage, current, temperature, and other critical

parameters in Li-Ion or Li-Polymer batteries, and

reports this information to the system host controller

over an SMBus v1.1 compatible interface.

2nd-level

safety

protection

for

overvoltage,

undervoltage, overtemperature, and overcharge

conditions, as well as hardware-based protection for

overcurrent in discharge and short circuit in charge

and discharge conditions.

Enhanced Charging

Adaptive Charging

•

Supports Two-Wire SMBus v1.1 Interface

SHA-1 Authentication

SHA-1 authentication with secure memory for

authentication keys enables identification of genuine

battery packs beyond any doubt.

Compact Package: 30-Lead TSSOP

The compact 30-lead TSSOP package minimizes

solution cost and size for smart batteries while

providing maximum functionality and safety for

battery gauging applications.
