Key Differentiators
- High-speed CAN transceiver with 1 Mbps data rate (vs ADM3052BRWZ)
- Short-circuit protection on CANH and CANL against shorts to power/ground in 24 V systems (vs ADM3052BRWZ)
- Slope control for reduced EMI (vs ADM3052BRWZ)
Design Notes
Place a 100 nF decoupling capacitor as close as possible to the VCC pin (pin 3) and ground. Additionally, a 10 Β΅F 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.
