2 Design Considerations

  • Prevents DC and unwanted AC currents between controller devices and peripheral ICs
  • Allows signal and power transfer between controller devices and peripheral ICs
  • Protects low voltage parts in a system from high voltage circuits
  • Diminishes the effect of ground potential difference
  • [FAQ] How to connect SPI MCU to multiple isolated SPI nodes?
  • [FAQ] How to calculate the maximum SPI speed supported by a digital isolator?
