The Texas Instruments BQ2012SN-D107 is a gas gauge integrated circuit intended for battery pack or in-system installation to accurately track available battery charge. It is designed for NiCd/NiMH rechargeable batteries and features a 1-wire (DQ) interface, 5 LED drivers, and slow-charge control.
This IC monitors the voltage drop across a sense resistor to determine charge and discharge activity. It estimates self-discharge based on an internal timer and temperature sensor, applying compensations for battery temperature and charge/discharge rates to provide accurate available charge information across various operating conditions. Battery capacity is automatically recalibrated during discharge cycles.
The BQ2012SN-D107 operates within a temperature range of 0°C to 70°C and is housed in a 16-pin SOIC package suitable for surface mounting. Its small size allows for implementations on as little as half a square inch of PCB space, making it ideal for battery pack integration.
Key features include conservative and repeatable measurement of available charge, charge control output, and a typical standby current of 120µA in self-discharge estimation mode. It can display capacity via a single-wire serial communication port or direct drive of LEDs.
