GENERAL DESCRIPTION

The ADM3055E/ADM3057E are 5 kV rms and 3 kV rms

isolated controller area network (CAN) physical layer transceivers

with integrated isolated dc-to-dc converters. The ADM3055E/

ADM3057E meet flexible data rate (CAN FD) requirements for

operation to 5 Mbps and higher and comply with the ISO 11898-2:

2016 standard. The ADM3055E/ADM3057E are capable of

supporting data rates as high as 12 Mbps.

The devices employ Analog Devices, Inc., iCoupler® technology

to combine a 3-channel isolator, a CAN transceiver, and an

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.

RECTIFICATION

Figure 1.

The ADM3055E/ADM3057E provide complete isolation

between the CAN controller and physical layer bus. Safety and

regulatory approvals (pending) for 5 kV rms isolation voltage,

10 kV surge test, and 8.3 mm creepage and clearance ensure the

ADM3055E meets application reinforced isolation requirements.

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 devices are

fully specified over an industrial temperature range of −40°C

to +105°C.
