EtherCAT P® One Cable for Power and EtherCAT® Reference Design


Design files


This reference design shows a physical implementation of the power couple in circuitry of an EtherCAT P® power sourcing device. The reference design is designed to meet all requirements from the official EtherCAT P implementation guide. This includes features like reverse polarity protection, in-rush current limit, and continuous current limit, all based on semiconductors from Texas Instruments.

  • EtherCAT® and power over one cable
  • Designed to meet EtherCAT P implementation guide
  • Input power protection against reverse polarity, overcurrent and more
  • Can be connected to any EtherCAT communication platform with an ethernet cable
  • Additional 5V/12V output for easy evaluation using AMIC110 ICE
