General Description

The bq2010 Gas Gauge IC is intended for battery-pack or in-system installation to maintain an accurate record of a battery's available 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.

NiMH and NiCd battery self-discharge is estimated based on an internal timer and temperature sensor.

Key Features

Conservative and repeatable measurement of available charge in rechargeable batteries.
Designed for battery pack integration - 120µA typical standby current - Small size enables imple- mentations in as little as 1 2 square inch of PCB.
Integrate within a system or as a stand-alone device - Display capacity via single- wire serial communication port or direct drive of LEDs.
Measurements compensated for current and temperature.
Self-disc.
