ADM3051CRZ-REEL7

Overview

The ADM3051CRZ-REEL7 is a high-speed industrial CAN transceiver compliant with the ISO 11898 standard, designed for 24 V systems. It operates on a single 5 V supply (4.5 V to 5.5 V) and supports data rates up to 1 Mbps. The device features short-circuit protection on CANH and CANL against shorts to power or ground. It includes three operating modes: high speed, slope control for EMI reduction, and low current standby. The component provides thermal shutdown protection and ensures unpowered nodes do not disturb the bus. It is available in an 8-lead SOIC package and functions within an industrial temperature range of -40°C to +125°C.

Feature Summary

• Integrated short-circuit protection safeguards CANH and CANL outputs against shorts to power or ground in 24 V systems.
• Slope control mode reduces electromagnetic interference by modifying signal rise and fall times, facilitating the use of unshielded cables.
• Low current standby mode minimizes power consumption while allowing wake-up capability via receiver activity.
• Thermal shutdown circuitry protects the device from excessive power dissipation during fault conditions.

Applications

• CAN data buses
• Industrial field networks
• DeviceNet applications
• CanOpen and CanKingdom implementations

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to reel packaging when sourcing components. Confirm that the Z suffix indicates RoHS compliance as specified in the manufacturer's ordering guide. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and adherence to the industrial temperature rating specifications.

Selection Notes

Select this component for applications requiring robust bus protection in 24 V industrial environments. Consider the slope control feature if EMI mitigation is critical without using shielded cabling. Verify that the system logic levels are compatible with the CMOS inputs and that the 5 V supply voltage aligns with the controller interface requirements.

Part Context

The ADM3051CRZ-REEL7 belongs to the ADM3051 series of CAN physical layer transceivers manufactured by Analog Devices. This series focuses on providing reliable communication interfaces for industrial networks. The CRZ variant specifically denotes the commercial/industrial temperature grade housed in an 8-lead SOIC package, distinguishing it from other package options or extended temperature variants within the same functional family.

Replacement Considerations

Direct pin-to-pin replacements within the same series include the non-reel version ADM3051CRZ. Other models in the broader product line may offer different isolation levels or voltage ranges but require schematic verification before substitution.
