This reference design implements a hardware interface based on the BiSS standard for position or rotary encoders. It supports both BiSS point-to-point and BiSS bus configurations. The building blocks include the power supply for a 5-V BiSS encoder with innovative smart eFuse technology and robust full-duplex RS-485 transceivers including line termination and EMC protection. An auxiliary power supply and logic level interface with adjustable I/O voltage level is provided to connect to subsequent MCUs and MPUs that would run the BiSS (or SSI) master protocol stack. This design is fully tested to meet EMC immunity requirements for ESD: fast-transient burst and surge according to IEC61800-3.
