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.
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.
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.
