Description

High serial cell count battery (>15s) systems are becoming more and more common for industrial applications. These applications are cost sensitive and require a simple solution that includes monitoring, protection, and control or even SOC (State of Charge) information rather than only basic independent hardware protection. This design offers a platform for the complete pack side solution. All independent hardware protection features are incorporated from the bq76930 and a robust communication interface is implemented for host device to read the battery information.

Features
  • Supports 16-Series to 20-series cell application
  • All independent hardware protecting function inherited from bq76930
  • Charger insertion detectable
  • Load removal detectable
  • Isolated differentiated CAN PHY for communication with host system
  • Supports up to 128k baud rate UART communication with external host
