General Description

The bq2011 Gas Gauge IC is intended for battery-pack 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 activity of the battery.

The bq2011 is designed for systems such as power tools with very high discharge rates.

Key Features

Conservative and repeatable measurement of available charge in rechargeable batteries.
Designed for portable equipment such as power tools with high discharge rates.
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 of PCB.
Direct drive of LEDs for capacity display.
Self-discharge compensation using internal temper.
