  • •Effective communication between domains.
  • •Open-load and short-circuit detection.
  • •Replacement of relays and fuses to reduce size while improving power efficiency.
  • •Improved thermal efficiency with optimized PCB layout.
  • •Optimization for battery transients and prevention of EMI.
