The BQ78350DBT is a CEDV Li-ion gas gauge and Battery Management Controller provides a comprehensive set of Battery Management System (BMS) subsystems, helping to accelerate product development for faster time-to-market. 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 controller 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.
