The ADM3057E is a 3 kV rms isolated controller area network (CAN) physical layer transceiver with an integrated isolated dc-to-dc converter. The ADM3057E meets flexible data rate (CAN FD) requirements for operation to 5 Mbps and higher and complies with the ISO 11898-2: 2016 standard. The ADM3057E is capable of supporting data rates as high as 12 Mbps.The device employs Analog Devices, Inc.,iCoupler®technology to combine a 3-channel isolator, a CAN transceiver, and an Analog DevicesisoPower®dc-to-dc converter into a single, surface-mount, small outline integrated circuit (SOIC) package. The device is powered by a single 5 V supply, realizing a fully isolated solution for CAN and CAN FD. Radiated emissions from the high frequency switching of the dc-to-dc convertors are kept below EN 55022 Class B limits by continuous adjustments to the switching frequency.The ADM3057E provide complete isolation between the CAN controller and physical layer bus. The ADM3057E has an isolation voltage of 3 kV rms and 7.8 mm creepage in a 20-lead, wide body SOIC.Low propagation delays through the isolation support longer bus cables. Slope control mode is available for standard CAN at low data rates. Standby mode minimizes power consumption when the bus is idle or if the node goes offline. Silent mode allows the TXD input to be ignored for listen only mode.Dominant timeout functionality protects against bus lock up in a fault condition. The current limiting and thermal shutdown features protect against output short circuits. The device is fully specified over an industrial temperature range of −40°C to +105°C.ApplicationsCANOpen, DeviceNet, and other CAN bus applicationsIndustrial automationProcess control and building controlTransport and infrastructure
