ADM3054BRWZ Обзор
A CAN transceiver is a device that interfaces between the CAN controller (e.g., a microcontroller with built-in CAN) and the physical differential bus. It converts the digital logic levels of the controller to the differential voltages required on the CAN bus and vice versa. Isolation is critical in harsh environments to protect the controller and users from high voltages, ground loops, and noise. The ADM3054 provides galvanic isolation up to 5 kV rms, ensuring safe and reliable communication in industrial automation, motor control, and electric vehicle applications.
Key features include 5 kV rms isolation, integrated DC-to-DC converter (for the BRWZ variant, it includes an integrated isolated power supply), bus protection up to ±58 V, and thermal shutdown. The device operates from a single 5 V supply on the logic side and a 5 V or 3.3 V supply on the bus side, with a typical data rate of 1 Mbps. It also features a high common-mode transient immunity of 25 kV/µs, ensuring robust operation in noisy environments.
The ADM3054 uses iCoupler technology, which uses chip-scale transformers to isolate signals, providing superior performance compared to optocouplers in terms of speed, power consumption, and reliability. The integrated DC-to-DC converter eliminates the need for an external isolated power supply, simplifying design and reducing board space. The device also includes a VIO pin for logic-level translation, allowing interface with 3.3 V or 5 V microcontrollers.
Typical applications include industrial fieldbus networks, motor control, HVAC systems, electric vehicle charging, and battery management systems. The high isolation voltage and robust bus protection make it ideal for applications where safety and reliability are paramount.
When designing with the ADM3054BRWZ, ensure proper PCB layout with adequate creepage and clearance distances for the isolation barrier. Place decoupling capacitors close to the VCC and VIO pins, and follow the recommended layout in the datasheet to achieve the specified isolation performance.

Заметки по проектированию
For the ADM3054BRWZ, maintain proper creepage and clearance distances under the SOIC-16 package to achieve the 5 kVrms isolation rating. Use a PCB with at least 8 mm creepage between the logic and bus sides. Place a 100 nF decoupling capacitor close to VCC and VIO pins, and a 10 µF capacitor on VISO output if using the integrated isolated power.
The ADM3054BRWZ dissipates minimal power, but in high-temperature environments, ensure adequate airflow or copper area for heat dissipation. The integrated DC-to-DC converter may generate some heat; keep the ambient temperature within the -40°C to +125°C range. For continuous operation at high data rates, monitor the junction temperature.
Do not exceed the absolute maximum ratings on the bus pins (CANH, CANL) beyond ±58 V. Ensure the logic supply (VCC) and bus supply (VISO) are properly decoupled. When using the integrated isolated power, do not load VISO beyond its specified current limit. Also, verify that the VIO pin voltage matches the microcontroller's logic level to avoid communication errors.
