Redundant CAN Reference Design
Description
This reference design demonstrates how to implement redundant (parallel) CAN for functional safety at the physical layer. It includes two SN65HVD257 CAN transceivers and additional logic to ensure both transceivers are receiving the same data.
Features
- Short propagation delays and fast loop times FAULT output pinI/O voltage range supports 3.3V and 5V MCU'sTXD and RXD dominant time outHBM ESD protection exceeds 12kVThis reference design is orderable
