nn Small 8-Lead 3mm Г— 3mm DFN Package The LTCВ®2944 measures battery charge state, battery voltage, battery current and its own temperature in portable
product applications. The wide input voltage range allows
use with multicell batteries up to 60V. A precision coulomb
counter integrates current through a sense resistor between
the battery’s positive terminal and the load or charger. …
