BQ2011 Description

Short technical summary and product information.

The BQ2011 Gas Gauge IC from Texas Instruments is engineered for battery-pack installations requiring precise tracking of available battery charge, particularly in systems like power tools that experience high discharge rates.

This IC monitors the voltage drop across a sense resistor to determine battery charge and discharge activity. It incorporates an internal temperature sensor for self-discharge compensation, applying corrections for battery temperature and charge/discharge rates to ensure accurate available charge information across various operating conditions. The device supports direct drive of LEDs for capacity display and features a simple single-wire serial communications port for subassembly testing.

Designed for integration into battery packs, the BQ2011 is suitable for rechargeable batteries and can operate directly from up to four cells. Its compact size enables implementations in small PCBs. The typical standby current is 120µA in self-discharge estimation mode.

Key specifications include a battery capacity range of 800mAh to 2000mAh, an operating voltage range of 3.0V to 6.5V, and an operating temperature range of 0°C to 70°C. The BQ2011 is supplied in a 16-pin narrow SOIC package.
