Description

The TIDA-00792 TI Design provides monitoring, balancing, primary protection and gauging for a 12 to 15 cell lithium-ion or lithium-iron phosphate based batteries. This board is intended to be mounted in an enclosure for industrial systems. The reference design subsystem provides battery protection and gauging configuration with parameters avoiding code development and provides high side protection switching to allow simple PACK- referenced SMBus communication for battery status even while protected.

Features
  • 12 to 15 cell li-ion and phosphate battery management system
  • High side protection switching using N-channel MOSFETs
  • Cell balancing for extended battery lfie
  • Gas gauging for estimation of system run-time
  • This sub-system circuit design is tested and includes GUI and getting started guide
