The BQ2011 Gas Gauge IC by Texas Instruments is engineered for battery-pack installations requiring accurate tracking of available charge, particularly in portable equipment 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 features a typical standby current of 120µA in self-discharge estimation mode and supports 2-4 series cells with a battery capacity range of 800mAh to 2000mAh. The operating temperature range is from 0°C to 70°C.
Key functionalities include self-discharge compensation using an internal temperature sensor, direct drive of LEDs for capacity display, and a simple single-wire serial communications port for subassembly testing. The BQ2011 is available in a compact 16-pin narrow SOIC package, enabling implementations in small PCB areas.
Designed for systems with very high discharge rates (>5A), the BQ2011 automatically learns actual battery capacity during discharge cycles and can display nominal available charge using a five-segment LED display. Compensations for battery temperature and charge/discharge rates ensure accurate information across various operating conditions.
