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
7.8mmx6.4mm 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-1st level and 2nd level
safety protection on overvoltage, undervoltage,
overtemperature, and overcharge, as well as
hardware-overcurrent in discharge, short circuit in
charge and discharge protection.
