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.

The IC monitors the 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.

Self-discharge of NiMH and NiCd batteries is estimated based on an internal timer and temperature sensor.

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.
