3 Description

The Texas Instruments bq3060 Battery Manager is a

fully integrated, single-chip, pack-based solution that

provides a rich array of features for gas gauging,

protection, and authentication for 2, 3, or 4 series cell

Li-Ion battery packs. With a footprint of merely 7.8

mm × 6.4 mm in a compact 24-pin TSSOP package,

the bq3060 maximizes functionality and safety while

dramatically cutting the solution cost and size for

smart batteries.

Using its integrated high-performance analog

peripherals, the bq3060 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 the

information to the system host controller over an

SMBus 1.1-compatible interface.

The bq3060 provides software-first level and second

level safety protection on overvoltage, undervoltage,

overtemperature, and overcharge, as well as

hardware-overcurrent in discharge, short circuit in

charge, and discharge protection.
