ADM3057E: 7.8 mm minimum with 20-lead SOIC W High common-mode transient immunity: >75 kV/s Industrial operating temperature range: 40C to +105C The ADM3055E/ADM3057E provide complete isolation APPLICATIONS between the CAN controller and physical layer bus. Safety and CANOpen, DeviceNet, and other CAN bus implementations regulatory approvals (pending) for 5 kV rms isolation voltage, Industrial automation 10 kV surge test, and 8.3 mm creepage and clearance ensure the Process control and building control ADM3055E meets application reinforced isolation requirements. Transport and infrastructure The ADM3057E has an isolation voltage of 3 kV rms and 7.8 mm creepage in a 20-lead, wide body SOIC. GENERAL DESCRIPTION Low propagation delays through the isolation support longer The ADM3055E/ADM3057E are 5 kV rms and 3 kV rms bus cables. Slope control mode is available for standard CAN at isolated controller area network (CAN) physical layer transceivers low data rates. Standby mode minimizes power consumption with integrated isolated dc-to-dc converters. The ADM3055E/ when the bus is idle or if the node goes offline. Silent mode ADM3057E meet flexible data rate (CAN FD) requirements for allows the TXD input to be ignored for listen only mode. operation to 5 Mbps and higher and comply with the ISO 11898-2: 2016 standard. The ADM3055E/ADM3057E are capable of Dominant timeout functionality protects against bus lock up in supporting data rates as high as 12 Mbps. a fault condition. The current limiting and thermal shutdown features protect against output short circuits. The devices are The devices employ Analog Devices, Inc., iCoupler technology fully specified over an industrial temperature range of 40C to combine a 3-channel isolator, a CAN transceiver, and an to +105C. Analog Devices isoPower dc-to-dc converter into a single, surface- mount, small outline integrated circuit (SOIC) package. The devices are 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. Rev.
