General Description

The Si834x provides up to four isolated 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).

Each switch is galvanically isolated for safety using Skyworks’ groundbreaking CMOS-based isolation technology, offering better reliability and performance than the traditional optocoupler-based isolation, including high Common-Mode Transient Immunity (CMTI) over 100 kV/µs.
