LM74720QDRRRQ1 is an automotive ideal-diode controller for external back-to-back N-channel MOSFETs, combining reverse-battery protection, load disconnect control, and adjustable overvoltage cutoff.

Best for

  • 12 V and 24 V automotive battery-powered ECUs
  • Reverse-battery protection with low operating current
  • Switched output and load-dump cutoff designs

Avoid if

  • A discrete MOSFET controller and external transient network cannot be accommodated
  • The required input voltage or transient condition exceeds the protected system design limits

Check before use

  • External MOSFET ratings and body-diode current capability
  • TVS clamping during ISO 7637-2 pulses
  • Overvoltage threshold divider and downstream voltage limits
  • RTN pad connection and boost-loop layout
