BQ78PL114RGZR Description

Short technical summary and product information.

The BQ78PL114RGZR from Texas Instruments is an advanced battery management controller IC. It is specifically designed for managing 3- to 8-series-cell Lithium Ion battery systems, with a firmware upgrade option supporting up to 12 series cells.

 

Key features include PowerPump technology for efficient charge transfer between cells, enhancing runtime and lifespan. It incorporates a high-resolution 18-bit integrating Delta-Sigma coulomb counter for accurate charge flow measurements and gas gauging. The device also includes multiple independent ADCs for simultaneous, synchronous measurement of pack current and individual cell voltages, temperature, and safety parameters.

 

SmartSafety features provide prevention, diagnosis, and fail-safe mechanisms, including optimal cell management, improved sensing of cell problems, and detection of event precursors. The operating temperature range is -40°C to 85°C. The IC is housed in a 48-VQFN (7x7) package and is designed for surface mounting.

 

With very low power consumption in active, standby, ship, and undervoltage shutdown modes, the BQ78PL114RGZR is suitable for various battery-powered applications requiring precise monitoring and management.
