ADM3053BRWZ

Overview

The ADM3053BRWZ is an isolated CAN physical layer transceiver with an integrated isoPower DC-to-DC converter. It complies with the ISO 11898 standard and utilizes iCoupler technology to combine a 2-channel isolator, CAN transceiver, and DC-to-DC converter in a single 20-lead wide-body SOIC package. The device operates on a single 5 V supply (VCC) and supports 3.3 V or 5 V logic levels (VIO). It achieves data rates up to 1 Mbps with high common-mode transient immunity exceeding 25 kV/µs. The component provides 2.5 kVrms signal and power isolation, features thermal shutdown protection, and includes slope control for EMI reduction.

Feature Summary

• Integrates isoPower isolated DC-to-DC converter for fully isolated power generation without external components
• Employs iCoupler technology to provide digital signal isolation across the barrier
• Includes slope control functionality to reduce electromagnetic interference emissions
• Features thermal shutdown circuitry to protect against output short circuits

Applications

• CAN data buses
• Industrial field networks

Procurement Notes

Verify the specific ordering suffix BRWZ corresponds to the wide-body 20-lead SOIC package configuration. Confirm that the procurement channel provides documentation referencing the Rev. F datasheet to ensure compliance with current regulatory approvals including UL 1577 and DIN EN IEC 60747-17. Ensure the source is authorized to prevent counterfeit components.

Selection Notes

Select this component when a fully isolated CAN interface is required with integrated power conversion. It is suitable for systems needing 2.5 kVrms isolation between logic and bus sides. Consider the 20-lead wide-body SOIC package constraints and PCB layout requirements for the internal transformer. Verify compatibility with 3.3 V or 5 V logic interfaces and check if slope control is necessary for EMI compliance.
