Characteristics

To transmit data between ICs within a system, on-board interfaces like I2C or SPI are well suited. However, if the communication is conducted over several boards, or even over longer distances, a galvanically isolated, differential solution is required. Isolated SPI offers a simple and low effort solution for this.

In case there is a high potential difference between transmitter and receiver, i.e. in battery management systems, then there are higher requirements for the galvanic isolation between the devices. For these use cases we can offer special signal transformers.
