LM74912QRGERQ1 is a 65 V automotive ideal-diode controller that drives two external N-channel MOSFETs for reverse-battery protection, load disconnect, UV/OV protection, and VDS-based short-circuit latch-off.

Best for

  • 12 V and 24 V automotive battery-powered ECUs
  • Reverse-battery and reverse-current protection
  • Power paths requiring load disconnect and fault indication

Avoid if

  • Applications requiring precision current measurement
  • Designs without provision for external back-to-back N-channel MOSFETs

Check before use

  • Validate external MOSFET safe operating area during short circuit and inrush.
  • Confirm transient clamp levels remain within IC and MOSFET ratings.
  • Keep the exposed RTN pad floating.
