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