Gas Gauge IC for Lithium Primary Cells
General Description
The bq2052 Lithium Primary Gas Gauge IC is intended for battery-pack or in-system installation to maintain an accurate record of available battery capacity. The IC monitors a voltage drop across a sense resistor connected in series with the cells to determine discharge activity of the battery. The bq2052 applies pensations for battery...
