BQ2014 - Gas Gauge

General Description

The bq2014 Gas Gauge IC is intended for battery-pack or in-system installation to maintain an accurate record of available battery charge.

Key Features

  • Conservative and repeatable measurement of available charge in rechargeable batteries.
  • Charge control output operates an external charge controller such as the bq2004 Fast Charge IC.
  • Designed for battery pack integration - 120µA typical standby current.
  • Display capacity via single-wire serial communication port or direct drive of LEDs.
  • Measurements compensated for current and temperature.
  • Self-discharge compensation using internal temperatur.
