ADM3053BRWZ - Isolated CAN Transceiver with isoPower | Analog Devices
MPN： ADM3053BRWZ ✓ 啟用中ADM3053BRWZ 概覽
An isolated CAN transceiver is a device that provides the physical layer interface between a CAN controller and the differential bus, while also providing electrical isolation between the two sides. This isolation protects the low-voltage logic side from high-voltage transients, ground loops, and common-mode noise that can occur on the bus. The integration of an isolated DC-to-DC converter eliminates the need for a separate isolated power supply, simplifying design and reducing board space. The ADM3053BRWZ is part of the broader family of isolated interface ICs, which includes isolated RS-485 transceivers and isolated digital isolators, all leveraging Analog Devices' iCoupler technology.
Key features of the ADM3053BRWZ include its compliance with ISO 11898, high-speed data rates up to 1 Mbps, and the ability to connect 110 or more nodes on the bus. It also offers slope control for reduced EMI, thermal shutdown protection, and high common-mode transient immunity. The device supports unpowered nodes, meaning that nodes without power do not disturb the bus, which is critical for fault-tolerant systems. The integrated isoPower DC-to-DC converter provides up to 500 mW of isolated power, which can be used to power the transceiver itself or external circuitry on the isolated side.
Technically, the ADM3053BRWZ uses iCoupler technology to achieve isolation, which uses chip-scale transformers to transmit data and power across the isolation barrier. This approach provides reliable isolation with high data rates and low power consumption compared to traditional optocoupler-based solutions. The device also features an internal split paddle lead frame on the bus side, which helps with thermal management and reduces parasitic inductance. The operating temperature range is -40°C to +125°C, making it suitable for harsh environments.
Typical applications include industrial fieldbus networks, building automation, automotive diagnostics, and medical equipment. In industrial automation, the ADM3053BRWZ is used to connect sensors and actuators to a CAN bus while providing isolation to protect the control system from electrical noise. In automotive applications, it is used for in-vehicle networking and diagnostics, where isolation is required to prevent ground loops and protect sensitive electronics.
When designing with the ADM3053BRWZ, it is important to place a low inductance ceramic capacitor close to the VCC and VIO pins, with the total lead length between the capacitor and the power supply pin not exceeding 10 mm. This ensures stable operation and minimizes noise. Additionally, the bus side should be properly terminated to match the characteristic impedance of the bus to prevent signal reflections.

設計說明
Place a low inductance ceramic capacitor (e.g., 0.1 µF) as close as possible to the VCC and VIO pins, with the total lead length between the capacitor and the power supply pin not exceeding 10 mm. This minimizes noise and ensures stable operation. Additionally, use a 10 µF electrolytic capacitor in parallel for bulk decoupling.
The ADM3053 features an internal split paddle lead frame on the bus side. Ensure the PCB has a corresponding thermal pad connected to the bus-side ground (GND2) to improve heat dissipation. Also, keep the CAN bus lines (CANH and CANL) as a differential pair with controlled impedance to minimize reflections and EMI.
Do not exceed the absolute maximum ratings for VCC and VIO. Ensure that the isolated side power (VISO) is properly decoupled with a capacitor to ground. Also, terminate the CAN bus with 120 Ω resistors at both ends to prevent signal reflections. Avoid running the bus lines near high-noise sources.
