GENERAL DESCRIPTION

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,

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.
