Description

The TIDA-00821 reference design is a stackable monitor and protector for use in large format Lithium-ion batteries that provides monitoring, balancing, and communications. Each bq76PL536A-Q1 EVM can manage 3 to 6 cells  for Li-ion battery applications. Up to 32 bq76PL536A-Q1 EVM modules can be stacked. The system provides fast cell balancing, diagnostics, and module to controller communication. Independent protection circuitry is
also integrated.

Features
  • Highly accurate monitoring and protection
  • Engineered for high system robustness
  • 1-Mb/s stackable vertical interface
  • Built in comparator for secondary OV, UV and OT protector
  • Cell balancing control output with safety timeout
