Isolated Smart Switches

Smart switches are ideal for driving resistive and inductive loads including solenoids, relays, and lamps commonly found in industrial control systems such as programmable logic controllers (PLC). Skyworks smart switch offerings are 24 Volt-compatible, rigorously comply to IEC61131-2, and respond robustly to fault conditions like open circuits, over-current, over-voltage, and over-temperature.

Si834X

Si834x devices provide up to four isolated high- or low-side switches with low "ON" state switch resistance. Si834x switches are ideal for driving resistive and inductive loads including solenoids, relays, and lamps commonly found in industrial control systems such as programmable logic controllers (PLC). Each switch is galvanically isolated for safety using Skyworks' groundbreaking CMOS based isolation technology.

Si830X

Si830x provides four high-side or low-side switches with low RON. These switches are ideal for driving resistive and inductive loads like solenoids, relays, and lamps commonly found in industrial control systems like Programmable Logic Controllers (PLC). They are easily interfaced directly to an MCU, or controlled through a digital isolator or optocoupler-based isolation barrier.
