BQ2010 Description
The bq2010 Gas Gauge IC is intended for battery-pack or in-system installation to maintain an accurate record of a battery's available charge. The IC monitors a voltage drop across a sense resistor connected in series between the negative battery terminal and ground to determine charge and discharge activity of the battery. NiMH and NiCd battery self-discharge is estimated based on an internal timer and temperature...
