Texas Instruments BQ2010SN-D107TRG4

Description
The bq2010 Gas Gauge IC is designed to accurately measure the available charge in rechargeable batteries. It is intended for battery-pack or in-system installation and monitors a voltage drop across a sense resistor to determine charge and discharge activity. The IC compensates for current, temperature, and self-discharge to provide accurate measurements across a wide range of operating conditions. Battery capacity is automatically recalibrated during discharge cycles.

Features
Conservative and repeatable measurement of available charge
Designed for battery pack integration
120uA typical standby current
Small size enables implementations in as little as 1 square inch of PCB
Integrates 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-discharge compensation using internal temperature sensor
Accurate measurements across a wide range of current (> 500:1)
16-pin narrow SOIC

Applications
Battery-powered devices
Battery packs
In-system battery monitoring
Battery management systems
