ADM3054BRWZ

Overview

The ADM3054BRWZ is a 5 kV rms signal isolated CAN transceiver compliant with the ISO 11898 standard. It integrates a 3-channel isolator and a high-speed CAN transceiver using iCoupler technology within a single wide-body, 16-lead SOIC package. The logic side operates on a 3.3 V or 5 V supply (VDD1), while the bus side requires a dedicated 5 V supply (VDD2). It supports data rates up to 1 Mbps and includes integrated protection against shorts to power or ground in 24 V systems. An integrated VDD2SENSE pin detects loss of power on the bus side. The device features thermal shutdown and current-limiting capabilities, operating over an industrial temperature range from −40°C to +125°C.

Feature Summary

• Provides 5 kV rms signal isolation between the logic controller and the physical layer bus using iCoupler technology.
• Includes integrated short-circuit protection on CANH and CANL pins for 24 V system environments.
• Features a VDD2SENSE output pin that signals when the bus-side power supply is lost.
• Supports unpowered nodes without disturbing the bus and allows connection of 110 or more nodes.

Applications

• CAN data buses
• Industrial field networks

Procurement Notes

Verify the specific ordering suffix to confirm packaging type and automotive qualification status. The BRWZ suffix indicates a tube package, while RL7 denotes a reel. Ensure the selected variant matches the required manufacturing quality standards for the target application environment.

Selection Notes

Select this component when signal isolation is required for CAN communication in noisy industrial environments. Verify that the system design provides separate 3.3 V/5 V logic power and a dedicated 5 V bus power supply. Confirm that the 1 Mbps data rate meets the network requirements and that the wide-body SOIC footprint fits the PCB layout constraints.

Part Context

The ADM3054 belongs to Analog Devices' family of isolated CAN transceivers designed for robust industrial communication. It utilizes proprietary iCoupler technology to achieve electrical isolation without magnetic components. This series addresses the need for reliable data transmission in electrically noisy environments where ground potential differences exist between controllers and bus segments.

Replacement Considerations

Direct replacements include other models within the ADM305x series, such as the ADM3052 or ADM3053, depending on the required isolation voltage level and power supply configuration. Verify compatibility regarding package dimensions and pinout assignments before substitution.
