Shenzhen Meiyuxin Technology Co., Ltd. supplies New Original BQ34110PWR Multi-Chemistry High Cell Count Battery Fuel Gauge 14-TSSOP -40 to 85 with Integrated Minimal Discharge Module! ! !

Product Description:

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.
