BQ2012 Gas Gauge IC

The bq2012 Gas Gauge IC is intended for battery-pack or in-system installation to maintain an accurate record of available battery 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 act.

BQ2012 Features

* ➤ Conservative and repeatable measurement of available charge in rechargeable batteries ➤ Charge control output ➤ Designed for battery pack integration - 120µA typical standby current (self-discharge estimation mode) - Small size enables imple- mentations in as little as 1 2 square inch
