bq2052 Overview
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 temperature and discharge rate to the available charge counter to provide...
