Applications
- Isolated CAN bus networks in industrial automation
- Telecom equipment with high voltage isolation
- Embedded systems requiring robust CAN protocol communication
- High EMI/ESD environments
How to Use
- Provide isolated power to each side: VDD1 (2.5–5.5V) and VDD2 (4.5–5.5V).
- Place a 0.1 µF decoupling capacitor close to each VDD pin.
- Use TXD pin for data input; ensure dominant timeout prevents bus hang-ups.
- Connect CANH and CANL to the CAN bus with proper termination.
- Observe thermal derating in high-temperature applications (< 200 ns loop delay).
