The datasheet says the MCP2561/MCP2562 is suitable for 12V and 24V systems except that everywhere I look in the datasheet it says VDD needs to be between 4.5 to 5V. How can CANH be greater than VDD or CANL be lower than VSS?? How would these internal MOSFETs work (shown on page 2 of datasheet) ?
Looking at CANH and CANL also got me wondering what are CANH and CANL referenced to? For example if I want to have a 12V CANbus, how do I get those lines to 12V - how are they pulled up/down?
