ADM3050EBRWZ-RL7 概述
A CAN transceiver is a device that provides the physical layer interface between a CAN controller and the differential bus lines. It converts the digital signals from the controller into differential signals for transmission over the twisted-pair bus and vice versa. In isolated CAN transceivers, galvanic isolation is provided between the controller side and the bus side to protect against ground potential differences, noise, and transient voltages. The ADM3050E belongs to the family of isolated CAN transceivers, which are essential in harsh environments where safety and reliability are critical.
Key features of the ADM3050EBRWZ-RL7 include 5.7 kV rms isolation voltage, integrated DC-to-DC converter for isolated power, and compliance with ISO 11898-2:2016. It supports CAN FD data rates up to 12 Mbps, ensuring high-speed communication. The device also passes EN 55022 Class B radiated emissions by 6 dB on a simple 2-layer PCB, eliminating the need for stitching capacitance or high-voltage SMT safety capacitors. This simplifies PCB layout and reduces BOM cost.
Technically, the ADM3050E employs iCoupler technology, which uses chip-scale transformers to provide isolation, offering superior performance compared to optocouplers in terms of speed, reliability, and power consumption. The integrated DC-to-DC converter provides isolated power to the bus side, eliminating the need for an external isolated power supply. The device operates over a wide temperature range and includes thermal shutdown and current limiting protection.
Typical applications include industrial fieldbus networks, building automation, motor control, and automotive electronics. The high isolation voltage and robust EMC performance make it ideal for systems where ground loops and noise are concerns. The ADM3050EBRWZ-RL7 is available in tape and reel packaging, suitable for high-volume production.
When designing with this device, ensure proper PCB layout to maintain isolation creepage and clearance distances. The integrated DC-to-DC converter requires careful placement of external components to minimize noise. Refer to the ADM3050E datasheet for detailed application information.

设计说明
For optimal EMC performance, follow the layout guidelines in the ADM3050E datasheet. The device passes EN 55022 Class B on a simple 2-layer PCB without stitching capacitance or high-voltage SMT safety capacitors. Ensure proper creepage and clearance distances for the 5.7kV isolation rating. Place the decoupling capacitors close to the VDD1 and VISO pins.
The integrated DC-DC converter requires careful selection of external components. Use a 10uF ceramic capacitor on VDD1 and a 1uF capacitor on VISO as recommended in the datasheet. Ensure the input supply can handle the peak current during startup. The DC-DC converter provides isolated power, eliminating the need for an external isolated supply.
Do not exceed the absolute maximum ratings for VDD1 and VISO. Ensure the CAN bus termination is correct (120 ohms at both ends). Avoid routing high-speed digital signals near the isolation barrier. For high-temperature applications, consider the ADM3050ETRWZ-EP-RL variant with extended temperature range.
