The Texas Instruments bq78350 Li-Ion and LiFePO4 Battery Management Controller and companion to the bq769x0 family of Analog Front End (AFE) protection devices provides a comprehensive set of Battery Management System (BMS) subsystems, helping to accelerate product development for faster time-to-market.

The bq78350 controller and the bq769x0 AFE support from 3-series to 15-series cell applications. The bq78350 provides an accurate fuel gauge and state-of-health (SoH) monitor, as well as cell balancing and a full range of voltage-, current-, and temperature-based protection features.

The bq78350 offers optional LED or LCD display configurations for the capacity reporting. It also makes data available over its SMBus 1.1 interface. Battery history and diagnostic data is also kept within the device in non-volatile memory and is available over the same interface.
