This reference design implements a hardware interface based on the HEIDENHAIN EnDat 2.2 standard for position or rotary encoders. The building blocks include the power supply for the encoder with innovative smart eFuse technology and robust half-duplex RS-485 transceivers including line termination and EMC protection. An auxiliary power supply and logic level interface with adjustable I/O voltage level are provided to connect to subsequent MCUs and MPUs that would run the EnDat 2.2 master protocol stack. This design is fully tested to meet EMC immunity requirements for ESD, fast transient burst and surge according to IEC61800-3.
