USER GUIDE
UG390: Si834x-EVB User Guide
Description
The Si834x-IF provides up to four isolated high-side
(sourcing) or low-side (sinking) switches with low R
These switches are ideal for driving resistive and induc-
tive loads such as solenoids, relays, and lamps com-
monly found in industrial control systems like PLCs.
Each switch is galvanically isolated for safety using Sky-
works Solutions' ground-breaking CMOS-based isola-
tion technology which enables easy interfacing with
low voltage 2.25 V MCUs and high CMTI (100 kV/µs).
The Si834x evaluation board allows designers to evalu-
ate Skyworks' Si834x family of Isolated Smart
Switches. Each board comes populated with one
Si834x device, LED status indicators, pluggable load
terminals for evaluation of the device's key parame-
ters, and test points for monitoring device pins. Addi-
tional information on the Si834x products can be
found at https://www.skyworksinc.com/Products/Iso-
lation. The product data sheet and application notes
can be referenced to help facilitate designs.
