- Compliance with ISO 11898 (vs ADM3053BRWZ-REEL7)
Design Notes
Place a low inductance ceramic capacitor (e.g., 0.1 Β΅F) 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 Β΅F 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 Ξ© resistors at both ends to prevent signal reflections. Avoid running the bus lines near high-noise sources.
