Si834x Isolated Smart Switches

Skyworks Solutions Inc. Si834x Isolated Smart 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). These switches are galvanically isolated for safety using CMOS-based isolation technology, resulting in better reliability, performance, and high common-mode transient immunity (CMTI) of over 150kV/μs. The logic interface for the Si834x supports low-power 2.25V MCUs and FPGAs. The switches offer a wide power supply range of 9V to 32V, making them ideal for a range of industrial digital voltage levels. Capable of providing up to 0.5A of IEC61131-2-compliant continuous current in a quad-channel configuration, Skyworks Solutions Inc. Si834x switches also provide 2.5A of continuous current in a single-channel configuration.
