3.2 Design Considerations

To pass BCI test, it is important to follow the three items:

  • Good input filter circuit can suppress the BCI noise, TI recommends to place input capacitors as close to device pins as possible.
  • Vias will introduce parasitic noise, TI recommends to use as less vias as possible especially on power traces.
  • Large GND polygon can provide a good noise path and thermal performance, TI recommends to merge GND together and keep it as large as possible.
