Signal and Power Isolated CAN Transceiver  
with Integrated Isolated DC-to-DC Converter  
Data Sheet  
ADM3053  
FEATURES  
GENERAL DESCRIPTION  
2.5 kV rms signal and power isolated CAN transceiver  
isoPower integrated isolated dc-to-dc converter  
5 V operation on VCC  
The ADM3053 is an isolated controller area network (CAN)  
physical layer transceiver with an integrated isolated dc-to-dc  
converter. The ADM3053 complies with the ISO 11898 standard.  
5 V or 3.3 V operation on VIO  
The device employs Analog Devices, Inc., iCoupler® technology  
to combine a 2-channel isolator, a CAN transceiver, and  
Analog Devices isoPower® dc-to-dc converter into a single  
SOIC surface mount package. An on-chip oscillator outputs a pair  
of square waveforms that drive an internal transformer to provide  
isolated power. The device is powered by a single 5 V supply  
realizing a fully isolated CAN solution.  
Complies with ISO 11898 standard  
High speed data rates of up to 1 Mbps  
Unpowered nodes do not disturb the bus  
Connect 110 or more nodes on the bus  
Slope control for reduced EMI  
Thermal shutdown protection  
High common-mode transient immunity: >25 kV/μs  
Safety and regulatory approvals  
The ADM3053 creates a fully isolated interface between the  
CAN protocol controller and the physical layer bus. It is capable  
of running at data rates of up to 1 Mbps.  
UL recognition  
2500 V rms for 1 minute per UL 1577  
VDE Certificate of Conformity  
The device has current limiting and thermal shutdown features  
to protect against output short circuits. The part is fully specified  
over the industrial temperature range and is available in a  
20-lead, wide-body SOIC package.  
DIN EN 60747-5-2 (VDE 0884 Part 2): 2003-01  
V
IORM = 560 V peak  
Industrial operating temperature range (−40°C to +85°C)  
Available in wide-body, 20-lead SOIC package  
The ADM3053 contains isoPower technology that uses high  
frequency switching elements to transfer power through the  
transformer. Special care must be taken during printed circuit  
board (PCB) layout to meet emissions standards. Refer to the  
AN-0971 Application Note, Control of Radiated Emissions with  
isoPower Devices, for details on board layout considerations.
