ADM3050EBRWZ - 5.7kV Isolated CAN-FD Transceiver | Analog Devices
MPN： ADM3050EBRWZ ✓ 啟用中ADM3050EBRWZ 概覽
A CAN transceiver is a physical layer device that connects a CAN controller to the differential bus lines (CANH and CANL). It converts the controller's logic-level signals to differential signals for transmission and vice versa for reception. In the system hierarchy, the ADM3050E sits between the CAN controller (often integrated in a microcontroller) and the twisted-pair bus, providing galvanic isolation to protect the controller and other low-voltage circuitry from high-voltage transients and ground potential differences.
Key features include 5.7 kV rms isolation voltage, compliance with ISO 11898-2:2016, support for CAN FD data rates up to 12 Mbps, and a 5V supply voltage. The device is available in a 16-lead SOIC package (SOIC-16) and is RoHS compliant. It is designed for industrial automation, building control, and automotive applications where robust communication and isolation are critical.
Technically, the ADM3050E uses iCoupler technology to combine isolation and transceiver functions, eliminating the need for external optocouplers and separate isolated power supplies. The device provides a fully isolated solution, with isolation between the CAN controller and the physical layer bus. It features a basic feature set, focusing on essential CAN communication without additional complexity.
Typical applications include industrial fieldbus networks, motor control systems, HVAC control, and electric vehicle charging stations. The high isolation voltage and CAN FD support make it suitable for harsh environments where noise and ground loops are common.
When designing with the ADM3050E, ensure proper PCB layout with adequate creepage and clearance distances for the isolation barrier. The device requires a 5V supply on both the logic side and the bus side, and external termination resistors may be needed depending on the bus configuration.

設計說明
For the ADM3050EBRWZ, ensure proper PCB layout with adequate creepage and clearance distances for the 5.7 kV rms isolation barrier. Maintain at least 8 mm creepage between the logic side and bus side to meet safety standards. Use a solid ground plane on each side of the isolation barrier and avoid routing traces across the barrier.
The ADM3050EBRWZ requires a 5V supply on both the logic side (VCC1) and the bus side (VCC2). Use separate power supplies or isolated DC-DC converters to maintain isolation. Decouple each supply pin with a 100 nF ceramic capacitor placed close to the pin, and a 10 uF bulk capacitor for transient currents.
Do not forget to connect the bus termination resistor (typically 120 ohms) at both ends of the CAN bus. The ADM3050EBRWZ does not include internal termination. Also, ensure the CANH and CANL lines are properly biased and that the bus is not left floating when the transceiver is disabled.
