BQ2012SN-D107TR Description

Short technical summary and product information.

The BQ2012SN-D107TR from Texas Instruments is a gas gauge IC specifically designed for NiCd and NiMH rechargeable batteries. It provides conservative and repeatable measurements of available battery charge, making it suitable for battery pack integration or in-system use.

 

This IC features a 1-wire (DQ) interface, 5 LED drivers for capacity display, and slow-charge control. It monitors battery charge and discharge activity by measuring the voltage drop across a sense resistor. Self-discharge is estimated using an internal timer and temperature sensor, with compensations applied for battery temperature and charge/discharge rates to ensure accurate available charge information across various operating conditions.

 

The BQ2012SN-D107TR comes in a 16-pin SOIC package and is designed for surface mount applications. It operates within a temperature range of 0°C to 70°C. The device also includes a charge control output and a typical standby current of 120µA in self-discharge estimation mode. Battery capacity is automatically recalibrated during discharge cycles.
