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.

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.

Product Detail

The EVAL-ADM3055EEBZ allows the user to evaluate the ADM3055E and the ADM3057E isolated signal and power transceivers for controller area network (CAN) or CAN with flexible data rate (CAN FD) networks. The EVAL-ADM3055EEBZ allows all of the input and output functions to work without the need for external components.

Based on the Analog Devices, Inc., iCoupler® technology, the ADM3055E and the ADM3057E integrate logic side on-off keying (OOK) signal isolation channels and an Analog Devices isoPower® dc-to-dc converter to provide regulated, isolated power that is well below EN55022 Class B limits when transmitting on a 2-layer printed circuit board (PCB) with ferrites.

The EVAL-ADM3055EEBZ comes populated with an ADM3055E.

Full specifications of the ADM3055E and the ADM3057E can be found in the ADM3055E and the ADM3057E data sheets, available from Analog Devices and must be consulted in conjunction with this user guide when using the EVAL-ADM3055EEBZ.

The EVAL-ADM3055EEBZ is compatible and can be used to evaluate the ADM3057E. The ADM3055E and the ADM3057E differ by package and isolation capabilities, but both devices are functionally equivalent for evaluation.

EVAL-ADM3055E-ARDZ

5 kV rms Signal and Power Isolated CAN Transceiver forCAN FD Arduino Shield

5 kV rms Signal and Power Isolated CAN Transceiver forCAN FD Arduino Shield

Features and Benefits

  • Supports CAN Flexible Data rate (CAN FD) communications port with an integrated isolated dc-to-dc converter
  • Auxiliary isolated digital channel for runtime configuration of the bus termination
  • Reduced power standby state and remote wake-up request supported
  • Form Factor Compatible with Arduino

Product Detail

EVAL-ADM3055E-ARDZ is an Arduino Uno compatible Shield for an isolated controller area network with flexible data rate (CAN FD) communications port. The circuit interfaces to the local development platform via Serial Peripheral Interface (SPI) providing a simple method to add field bus communication to new and existing designs. EVAL-ADM3055E-ARDZ enables both the higher bandwidth CAN FD data rates (up to 8Mbps) demanded by modern multi-node CAN FD networks and the rugged electromagnetic compatibility (EMC) performance required by industrial environments.

The circuit uses the integrated auxiliary isolated digital channel of the ADM3055E transceiver for runtime configuration of the bus termination. The switchable termination circuitry connects a 120 Ω split termination with common-mode filtering capacitor between the CAN FD bus lines. Switchable termination allows on-the-fly software configuration of termination locations when the CAN FD bus is physically altered. Using switchable termination, each node can be used at any physical location without mechanical changes to the nodes and software can track the position of terminations in the network.

Additionally, the circuit can be set by the development platform to a reduced power standby state. While in the standby state, the isolated CAN FD communications port will notify the development platform of a remote wake-up request being transmitted by a remote CAN FD node to the CAN FD bus.

With the ADM3055E CAN FD transceiver, the circuit provides reinforced signal and power isolation between the node and CAN FD bus. Electrical connection to the CAN FD bus may be made either by screw terminal or the CAN CiA 303-1 male 9-pin sub-D port. Because the ADM3055E transceiver has an integrated isolated dc-to-dc converter, it does not require external power to be present on the CAN FD bus. The examples focus on CAN FD networks however this circuit is backwards compatible with classical CAN networks.
