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.
