STMicroelectronics recommends a 2-layer or 4-layer PCB with a thermal pad connected to a large copper area on the bottom layer to dissipate heat efficiently.
To ensure EMC, use a shielded cable for the bus interface, keep the PCB layout compact, and use a common mode choke or ferrite bead on the power lines.
The maximum allowed voltage on the VCC pin is 5.5V, exceeding which may damage the device.
Check the bus voltage, signal integrity, and termination resistors. Use a logic analyzer or oscilloscope to verify signal quality and timing.
The VN5050AJ-E is rated for operation up to 125°C, but thermal derating applies above 85°C. Ensure proper heat sinking and thermal management for reliable operation.
