Illustrative Applications
Isolated CAN
In today’s CAN networks, node-to-node isolation is increasingly recommended by designers to reduce EMI susceptibility, especially in high-
speed applications and in hybrid and electrical vehicle networks, where the 12 V battery has been replaced with one of several hundred volts.
Operator and equipment safety becomes critical when a high voltage source, such as the battery, needs to be connected to diagnosis systems
during routine maintenance procedures. In the application shown above, the microcontroller is isolated from the CAN transceiver by an IL712 or
IL721, allowing higher speed and more reliable bus operation by eliminating ground loops and reducing susceptibility to noise and EMI events.
The best-in-class 10 ns typical IL712/IL721 propagation delay minimizes CAN loop delay and maximizes data rate over any given bus length.
The simple circuit works with any CAN transceiver with a TxD dominant timeout, which includes all of the current-generation transceivers.
Isolated PROFIBUS / RS-485
NVE offers a unique line of PROFIBUS / RS-485 transceivers, but IL700 high-speed digital signal isolators can also be used as part of multi-chip
designs with non-isolated PROFIBUS transceivers.
