5.7 kV rms, Signal Isolated, Basic CAN FD Transceiver

The ADM3050E is a 5.7 kV rms isolated controller area network (CAN) physical layer transceiver with a high performance, basic feature set. The ADM3050E fully meets the CAN flexible data rate (CAN FD) ISO 11898-2:2016 requirements and is further capable of supporting data rates as high as 12 Mbps.

The device employs Analog Devices, Inc., iCoupler® technology to combine a 2-channel isolator and a CAN transceiver into a single small outline integrated circuit (SOIC) surface-mount package. The ADM3050E is a fully isolated solution for CAN and CAN FD applications. The ADM3050E provides isolation between the CAN controller and physical layer bus. Safety and regulatory approvals (pending) for a 5.7 kV rms withstand voltage, an 849 VPEAK working voltage, and a 12.8 kV surge test, ensure that the ADM3050E meets application isolation requirements.

Low loop propagation delays and the extended common-mode range of ±25 V support robust communication on longer bus cables. Dominant timeout functionality protects against bus lock up in a fault condition, and current limiting and thermal shutdown features protect against output short circuits. The CAN bus input and output pins are protected to ±40 V against accidental connection to a +24 V bus supply. The device is fully specified over the −40°C to +125°C industrial temperature range.
