LM74704QDDFRQ1 is an automotive ideal-diode controller that drives an external N-channel MOSFET for low-loss reverse-polarity protection and active ORing.

Best for

  • Automotive reverse-polarity protection
  • Active ORing
  • Automotive 12 V or 24 V power rails

Avoid if

  • A solution without an external N-channel MOSFET is required
  • A push-pull FET status output is required

Check before use

  • External MOSFET VDS and VGS ratings
  • TVS selection for ISO transient requirements
  • Open-drain FETGOOD pull-up voltage and resistor
  • MOSFET thermal dissipation and PCB current path
