ADM3051BRWZ - High Speed Industrial CAN Transceiver | Analog Devices
MPN： ADM3051BRWZ ✓ 啟用中ADM3051BRWZ 概覽
A CAN transceiver is a physical layer device that interfaces between a CAN protocol controller and the differential bus lines (CANH and CANL). It converts the digital signals from the controller into differential signals for transmission over the twisted-pair bus and vice versa. The transceiver is a critical component in the CAN network hierarchy, which spans from the application layer down to the physical layer. The ADM3051BRWZ specifically implements the physical layer, providing the necessary drive strength, receiver sensitivity, and protection features required for robust communication in harsh industrial environments.
Key features of the ADM3051BRWZ include its compliance with ISO 11898, which ensures interoperability with other standard CAN devices. The device supports data rates up to 1 Mbps, making it suitable for high-speed industrial control applications. Its short-circuit protection on CANH and CANL against shorts to power or ground in 24 V systems enhances robustness in industrial settings where wiring faults are common. The slope control feature allows the designer to reduce electromagnetic interference (EMI) by controlling the slew rate of the output signals, which is particularly useful in applications with stringent EMC requirements. Thermal shutdown protection prevents damage from excessive power dissipation, and the low current standby mode reduces power consumption when the bus is idle.
From a technical perspective, the ADM3051BRWZ is designed to handle the electrical stresses of industrial environments. Its differential output voltage and receiver input sensitivity are optimized for reliable communication over long bus lengths (up to 1 km) and with many nodes. The device's common-mode input range accommodates ground potential differences between nodes, which is common in distributed systems. The transceiver's propagation delay and loop delay are carefully controlled to ensure timing compliance with the CAN protocol, even at 1 Mbps. The device also features a silent mode (via the RS pin) that disables the transmitter, allowing for bus monitoring without driving the bus.
Typical applications for the ADM3051BRWZ include industrial automation, building automation, automotive electronics (non-safety critical), and any system requiring robust CAN communication. In industrial automation, it is used in PLCs, sensors, and actuators to provide reliable data exchange over long distances. In building automation, it enables communication between HVAC controllers, lighting systems, and access control panels. The device's high-speed capability and robustness make it ideal for these applications.
When designing with the ADM3051BRWZ, it is important to consider proper bus termination (typically 120 ohms at each end) and to use twisted-pair cabling to minimize EMI. The slope control pin (RS) can be used to adjust the slew rate for EMI reduction, but this also limits the maximum data rate. For 1 Mbps operation, the slope control should be set to high-speed mode (RS connected to ground). Additionally, the VCC supply should be decoupled with a 100 nF capacitor close to the VCC pin to ensure stable operation.

主要差異化特點
- High-speed CAN transceiver with 1 Mbps data rate (對比ADM3052BRWZ)
- Short-circuit protection on CANH and CANL against shorts to power/ground in 24 V systems (對比ADM3052BRWZ)
- Slope control for reduced EMI (對比ADM3052BRWZ)
設計說明
Place a 100 nF decoupling capacitor as close as possible to the VCC pin (pin 3) and ground. Additionally, a 10 µF bulk capacitor is recommended on the VCC rail to handle transient currents. The CANH and CANL lines should be routed as a differential pair with controlled impedance (typically 120 ohms) to minimize reflections and EMI. Keep the trace lengths short and avoid stubs to maintain signal integrity.
Use the slope control (RS pin) to adjust the slew rate of the CAN output signals. For high-speed operation (1 Mbps), connect RS to ground to select the high-speed mode. For lower data rates, a resistor from RS to ground can be used to reduce EMI. This is particularly important in applications with strict EMC requirements, such as automotive and industrial environments.
Ensure proper bus termination: place a 120 ohm resistor at each end of the CAN bus to match the characteristic impedance of the twisted-pair cable. Incorrect termination can cause signal reflections and communication errors. Also, avoid connecting more than 110 nodes without considering the total bus load and capacitance. The ADM3051BRWZ is not isolated; for applications requiring galvanic isolation, consider the ADM3052BRWZ or ADM3053BRWZ.
