3 Description
The bq34z653 SBS-compliant gas gauge and
protection IC, incorporating patented Impedance
Track™ technology, is a single IC solution designed
for battery-pack or in-system installation. The
bq34z653 measures and maintains an accurate
record of available charge in Li-Ion or Li-Polymer
batteries using its integrated high-performance
analog peripherals. The bq34z653 monitors capacity
change, battery impedance, open-circuit voltage, and
other critical parameters of the battery pack, which
reports the information to the system host controller
over a serial-communication bus. Together with the
integrated analog front-end (AFE) short-circuit and
overload protection, the bq34z653 maximizes
functionality and safety while minimizing external
component count, cost, and size in smart battery
circuits.
The implemented Impedance Track gas gauging
technology continuously analyzes the battery
impedance, resulting in superior gas-gauging
accuracy. This enables remaining capacity to be
calculated with discharge rate, temperature, and cell
aging—all accounted for during each stage of every
cycle with high accuracy.
