Ideal diode & ORing controllers

Our ideal diodes and ORing controllers offer space-saving and scalable solutions to protect your system against reverse voltage or reverse current. These devices significantly reduce the energy typically lost across the forward voltage drop of traditional discrete silicon or Schottky diodes.

Power efficiency

Reduce the energy loss from traditional discrete or Schottky diodes.

  • Low voltage drop
  • Low Iq
  • Thermal optimization


Improve your system's reliability with comprehensive power path and redundant power supply protection.

  • Reverse polarity protection
  • Reverse current blocking
  • Load dump and surge protection

Space saving

Optimize your system with scalable controllers or fully integrated ideal diodes.

  • N-FET controller
  • Integrated charge pump
  • Integrated FET
