ADM3054WBRWZ-RL7

Overview

The ADM3054WBRWZ-RL7 is a 5 kV rms signal isolated CAN transceiver compliant with the ISO 11898 standard. It integrates a 3-channel iCoupler isolator and a high-speed CAN transceiver in a single 16-lead wide-body SOIC package. The logic side (VDD1) supports 3.3 V or 5 V operation, while the bus side (VDD2) requires a 5 V supply. It achieves data rates up to 1 Mbps with propagation delays of 90 ns (TxD on to bus active). Integrated bus protection includes short-circuit protection against shorts to power/ground in 24 V systems, thermal shutdown at 150°C, and a VDD2SENSE pin for detecting loss of power on the bus side.

Feature Summary

• Integrates 5 kV rms signal isolation using iCoupler technology within a single package
• Provides integrated bus protection including short-circuit protection and thermal shutdown
• Features VDD2SENSE output for monitoring bus-side power status
• Supports unpowered nodes without disturbing the CAN bus

Applications

• CAN data buses
• Industrial field networks

Procurement Notes

Verify the specific ordering suffix RL7 indicates reel packaging containing 400 units. Confirm the W suffix denotes automotive qualification and halide-free construction. Ensure the component matches the Rev E datasheet specifications for insulation characteristics and regulatory approvals before finalizing procurement orders.

Selection Notes

Select this model when 5 kV rms signal isolation is required between the logic controller and the CAN physical layer. It is suitable for applications needing independent 3.3 V or 5 V logic supplies alongside a dedicated 5 V bus supply. The integrated VDD2SENSE feature aids in system diagnostics for power loss detection on the isolated bus side.

Part Context

The ADM3054 series represents Analog Devices' first signal-isolated CAN transceiver. The WBRWZ-RL7 variant specifically targets automotive applications with controlled manufacturing standards. It utilizes iCoupler technology to combine digital isolation and transceiver functions, distinguishing it from non-isolated CAN transceivers like the MAX3054.

Replacement Considerations

The ADM3054BRWZ-RL7 is the commercial grade equivalent without automotive qualification. Non-isolated alternatives such as the MAX3054ASD lack the 5 kV isolation barrier and VDD2SENSE functionality.
