BQ2011 - Gas Gauge IC

General Description

The bq2011 Gas Gauge IC is intended for battery-pack installation to maintain an accurate record of available battery charge.

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.
