BQ2050SN-D119TR Description

Short technical summary and product information.

The BQ2050SN-D119TR is a Lithium Ion gas gauge IC from Texas Instruments, intended for battery pack or in-system installation to accurately track available battery capacity. It monitors voltage drop across a sense resistor to determine charge and discharge activity, compensating for temperature and charge/discharge rates.

 

This IC supports a 1-wire (DQ) interface and includes 5 LED drivers for direct capacity indication. It operates with a typical current of 120µA and is housed in a 16-pin SOIC package, enabling small PCB implementations. The device automatically recalibrates capacity during discharge cycles.

 

Key features include conservative and repeatable capacity measurement, compensation for current and temperature, and self-discharge compensation using an internal temperature sensor. The operating temperature range is -20°C to 70°C. The package is a 16-SOIC (0.154", 3.90mm Width) suitable for surface mounting.
