ADM3055EBRWZ 概述
A CAN transceiver is the physical layer interface between a CAN controller and the differential bus lines (CANH and CANL). It converts the controller's logic-level signals to differential signals for transmission and receives differential signals back to logic levels. In industrial and automotive environments, galvanic isolation is often required to protect controllers from ground loops, voltage transients, and noise. The ADM3055E integrates this isolation, eliminating the need for external isolation components and simplifying PCB design.
Key features include 5 kV rms isolation, compliance with ISO 11898-2:2016 for CAN FD, data rates up to 12 Mbps, a VIO pin for 1.7 V to 5.5 V logic levels, extended common-mode range of ±25 V, and bus fault protection of ±40 V on CANH and CANL pins. The device also supports low-power standby with remote wake request, making it suitable for power-sensitive nodes.
The ADM3055E uses Analog Devices' iCoupler and isoPower technologies, which use chip-scale transformers to transmit data and power across the isolation barrier. This approach provides reliable isolation with low propagation delay (150 ns maximum loop) and high common-mode transient immunity. The integrated DC-to-DC converter eliminates the need for a separate isolated power supply, reducing component count and board space.
Typical applications include industrial fieldbus networks, building automation, automotive diagnostics, and any system requiring robust, isolated CAN communication. The wide logic-level range and high data rate make it versatile for both legacy CAN and newer CAN FD designs.
When designing with this device, ensure proper PCB layout for the isolation barrier and provide adequate decoupling on both the logic and bus sides. The integrated converter requires careful thermal management at high data rates and loads.

设计说明
Maintain a clear isolation barrier on the PCB between the logic side (pins 1-12) and the bus side (pins 13-20). Use a minimum creepage distance of 8 mm for 5 kV rms isolation. Place decoupling capacitors (0.1 µF and 10 µF) close to VCC and VISO pins. Avoid routing traces across the isolation barrier.
The integrated isoPower DC-DC converter generates heat, especially at high data rates and loads. Ensure adequate copper area on the PCB for heat dissipation. The SOIC-W package has a thermal resistance of approximately 40°C/W. For continuous operation at 12 Mbps, consider adding thermal vias under the package.
Do not exceed the absolute maximum ratings for VCC (7V) or VIO (6V). Ensure the VIO pin is powered before or simultaneously with VCC to avoid latch-up. The STBY pin must be properly terminated; floating it can cause unintended standby mode. Use proper termination resistors (120 Ω) on the CAN bus to prevent signal reflections.
