ADM3052BRWZ-REEL7

Overview

The ADM3052BRWZ-REEL7 is an isolated CAN transceiver with an integrated high-voltage, bus-side linear regulator. It complies with the ISO 11898 standard and supports data rates up to 1 Mbps. The device employs iCoupler technology to combine a 3-channel isolator, CAN transceiver, and linear regulator into a single package. It operates on a logic supply (VDD1) of 3.3 V or 5 V and a bus supply (V+) ranging from 11 V to 25 V. Key specifications include a common-mode transient immunity greater than 25 kV/µs, short-circuit protection on bus pins, and thermal shutdown. It is housed in a wide-body, 16-lead SOIC package.

Feature Summary

• Integrated bus-side linear regulator for power isolation
• High common-mode transient immunity exceeding 25 kV/µs
• Built-in miswire and short-circuit protection on bus pins
• Unpowered nodes do not disturb the bus

Applications

• CAN data buses
• Industrial field networks
• DeviceNet applications

Procurement Notes

Verify the ordering suffix REEL7 indicates reel packaging rather than tube. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the component matches the Rev C datasheet specifications regarding insulation ratings and operating temperature ranges before finalizing procurement orders.

Selection Notes

Select this component when a fully isolated CAN interface powered directly from the bus voltage is required. It is suitable for applications needing high common-mode transient immunity and integrated bus-side regulation. Consider the 16-lead wide-body SOIC package constraints and the requirement for external resistors for the linear regulator during circuit design.

Part Context

The ADM3052 series utilizes Analog Devices' iCoupler technology to provide magnetic isolation without optocouplers. This family includes variants like the ADM3053 and ADM3054. The BRWZ suffix denotes the industrial temperature range and specific package type. The REEL7 suffix specifically identifies the tape and reel packaging format for automated assembly.
