LM74700MDDFREP is an active ideal diode controller that drives an external N-channel MOSFET for low-loss reverse-polarity protection or power OR-ing.

Best for

  • Low-loss reverse-polarity protection
  • Redundant power OR-ing
  • 12 V, 24 V, and 48 V DC bus protection

Avoid if

  • A complete protection solution without an external MOSFET is required
  • MOSFET transient and inrush ratings cannot be validated

Check before use

  • Confirm ANODE, CATHODE, and MOSFET voltage stress during fault transients
  • Confirm the selected MOSFET tolerates the approximately 13 V gate drive or add a VGS clamp
  • Keep the gate-drive trace short and low resistance
