Design Notes
Ensure proper PCB layout with adequate creepage and clearance distances (at least 8 mm) between the isolated and non-isolated sides. Place decoupling capacitors (0.1 µF and 10 µF) close to the VCC and VISO pins. Use a solid ground plane on both sides of the isolation barrier.
The integrated DC-DC converter requires an external transformer and rectifier circuit as specified in the datasheet. Use low-leakage inductors and Schottky diodes for efficiency. Ensure the isolated output voltage is regulated to 5V and decoupled with a 10 µF capacitor.
Do not exceed the absolute maximum ratings for supply voltage and bus pin voltages. Ensure proper termination on the RS-485 bus to avoid reflections. The device has thermal shutdown, but adequate thermal relief should be provided on the PCB to prevent overheating.
