The bq2052 Lithium Primary Gas G a u g e I C is in t en d ed f or b a ttery-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 compensations for battery temperature and discharge rate to the available charge counter to provide available capacity information across a wide range of operating conditions.
