Conclusion

This application note illustrates how designers can maximize SCLT3-8 performances in their

applications especially in the fields of bus controller interface configurations, thermal

behavior and EMI robustness. They will find information that helps them to design new

system boards while saving time.

Designed for digital I/O module in factory automation, the SCLT3-8 is a low-loss EMI-proof

solution showing high usage flexibility. With the SCLT3-8, designers will be able to develop

highly integrated modules interfacing proximity sensors with the following benefits:

●

Reduced pin count

●

Saved space (only 3 isolation devices for SPI)

●

Reduced dissipation

●

No need for additional LED supply

●

Common SPI availability

●

EMI proof

To illustrate its performances and advantages, an evaluation board STEVAL-IFP000V1

using 2 SCLT3-8s configured in daisy chain is available with an optimized layout.
