Product Overview
ADM3053BRWZ-REEL7 is an isolated CAN physical-layer transceiver that integrates iCoupler signal isolation and an isoPower isolated dc-to-dc converter. It creates a galvanically isolated interface between a CAN protocol controller and the physical bus without requiring a separate isolated power module for the transceiver side.
The device supports CAN data rates up to 1 Mbps. VCC operates at 5 V while VIO can be 3.3 V or 5 V, which is an important interface detail when a 3.3 V controller must communicate with an isolated 5 V CAN transceiver stage.
Key Features
- 2.5 kV rms signal-and-power isolation.
- ISO 11898 CAN transceiver operation up to 1 Mbps.
- 3.3 V or 5 V VIO for logic-side compatibility.
- Slope control and thermal shutdown protection.
Functional Highlights
The separate VIO pin prevents logic-level compatibility from being tied to the 5 V CAN transceiver supply. This is particularly useful when the protocol controller is in a 3.3 V domain.
Integrated isolated power reduces external isolation components, but the board still needs isoPower-aware placement, decoupling, and emissions control.
Application Fit
- Isolated CAN data buses.
- Industrial field networks using CAN communication.
- Controller-to-bus interfaces requiring both signal and power isolation.
Design Considerations
- Keep VCC and VIO roles distinct during schematic review.
- Use the correct CAN termination for the actual network topology and bit rate.
- Follow isoPower PCB-layout guidance to control radiated emissions.
- Verify the RW-20 package and isolation clearances before layout release.
