3 Description
The bq34110 CEDV Battery Gas Gauge provides
CEDV gas gauging and End-Of-Service (EOS)
Determination for single- and multi-cell batteries. The
device includes enhanced features to support
applications where the battery is kept fully charged
and is rarely discharged, such as found in a wide
variety of backup systems. The bq34110 gas gauge
supports multiple battery chemistries, including Li-Ion
and LiFePO4, lead acid (PbA), Nickel Metal Hydride
(NiMH), and Nickel Cadmium (NiCd).
The gas gauging function uses voltage, current, and
temperature data with Compensated End-of-
Discharge Voltage (CEDV) technology to provide
State-Of-Charge (SOC) and State-Of-Health (SOH)
data. The gas gauge also incorporates an End-Of-
Service (EOS) Determination function that alerts
when battery capability has degraded and is
approaching the conclusion of its usable service.
The data available from the gauge can be read by the
host through a 400-kHz I2C bus. Two ALERT outputs
are also available to interrupt the host or can be used
for other functions, based on a variety of configurable
options.
