AEC-Q100ideal diode controllerreverse polarity protectionactive OR-ingN-channel MOSFETSOIC-8

LM74700QDRQ1 is an automotive ideal-diode controller that drives an external N-channel MOSFET for low-loss reverse-polarity protection or active OR-ing.

Best for

  • Automotive battery reverse-polarity protection
  • Low-loss active OR-ing
  • 12 V, 24 V, and 48 V DC power rails

Avoid if

  • A complete reverse-polarity solution without an external MOSFET is required
  • The system cannot tolerate body-diode conduction while EN is low

Check before use

  • Verify ANODE, CATHODE, and EN voltage limits under all transients
  • Use an external MOSFET with at least 15 V VGS capability or provide VGS clamping
  • Validate the TVS and output hold-up capacitor for the application
