Description

The Texas Instruments bq78350-R1 Li-Ion and LiFePO4 Battery ManagementController and companion to the bq769x0 family of Analog Front End (AFE) protection devicesprovides a comprehensive set of Battery Management System (BMS) subsystems, helping to accelerateproduct development for faster time-to-market.

The bq78350-R1controller and the bq769x0 AFE support 3-series to 15-series cell applications. Thebq78350-R1 device provides anaccurate fuel gauge and state-of-health (SoH) monitor, as well as cell balancing and a full rangeof voltage-, current-, and temperature-based protection features.

The bq78350-R1device offers optional LED or LCD display configurations for capacity reporting. It alsomakes data available over its SMBus 1.1 interface. Battery history and diagnostic data is also keptwithin the device in non-volatile memory and is available over the same interface.
