The BQ2014SN-D120TR from Texas Instruments is a Battery Gas Gauge IC intended for battery-pack or in-system installation to maintain an accurate record of available battery charge. This IC is suitable for NiCd and NiMH battery chemistries, supporting 2-4 series cells.
It features a capacity range from a minimum of 500 mAh to a maximum of 6000 mAh. The operating temperature range is from 0°C to 70°C. The device utilizes a Coulomb counter for measurement and includes external capacity indication via LEDs. Communication is handled through a single-wire DQ interface.
Designed for pack integration, the BQ2014SN-D120TR monitors voltage drop across a sense resistor to determine charge and discharge activity. It compensates for battery temperature and charge/discharge rates, and self-discharge is estimated using an internal timer and temperature sensor. The IC also includes a charge control output that can operate an external fast-charge IC, such as the bq2004.
The BQ2014SN-D120TR comes in a 16-SOIC package and is surface-mounted. Its typical standby current is 120 µA.
