ADM3055EBRWZ-RL7 Overview
A CAN transceiver is a physical layer device that connects a CAN controller to the differential bus lines (CANH and CANL). It converts the digital signals from the controller into differential signals for transmission and vice versa. Isolation in a CAN transceiver provides galvanic isolation between the bus side and the logic side, protecting sensitive electronics from ground loops, voltage spikes, and noise. The ADM3055E integrates the isolation barrier and DC-to-DC converter, eliminating the need for external isolated power supplies.
Key features include 5 kV rms isolation, an integrated isolated DC-to-DC converter, a VIO pin for 1.7 V to 5.5 V logic levels, low maximum loop propagation delay of 150 ns, extended common-mode range of ±25 V, and bus fault protection of ±40 V on CANH and CANL pins. It also supports low power standby with remote wake, making it ideal for power-sensitive nodes.
The ADM3055E uses Analog Devices' isoPower technology, which integrates a DC-to-DC converter with the signal isolation, providing a complete isolated CAN solution in a single package. This reduces board space and component count compared to discrete isolation solutions. The device is designed to meet the stringent requirements of CAN FD, ensuring reliable communication at high data rates.
Typical applications include industrial automation, building automation, motor control, and automotive electronics. The integrated isolation and DC-to-DC converter simplify design and improve reliability in harsh environments. The device is also suitable for battery management systems and other applications requiring isolated CAN communication.
When designing with the ADM3055E, ensure proper PCB layout for the isolation barrier and provide adequate decoupling on the VIO and VCC pins. The integrated DC-to-DC converter requires careful consideration of the external components, such as the transformer and rectifier, to achieve optimal performance.

Design Notes
For optimal isolation performance, maintain a clearance of at least 8 mm between the logic side (pins 1-8) and the bus side (pins 9-16) on the PCB. Use a ground plane split under the device to prevent noise coupling. Place decoupling capacitors (0.1 µF and 10 µF) close to VCC and VIO pins.
The integrated DC-DC converter requires an external transformer and rectifier circuit. Refer to the ADM3055E datasheet for the recommended transformer (e.g., Wurth Elektronik 750313771) and output capacitor values. Ensure the transformer is rated for the required isolation voltage (5 kV rms) to maintain safety.
The ADM3055E dissipates power internally due to the integrated DC-DC converter. At maximum data rate and load, the junction temperature can rise significantly. Ensure adequate copper area on the PCB for heat dissipation. The thermal resistance (θJA) is approximately 80°C/W; calculate the junction temperature for your application.
