Isolation and Powers by Skyworks

Each of our digital isolator product families is designed and continuously adapted to serve specific industry applications. Each ship with Skyworks’ proprietary CMOS capacitive isolation technology. Customers can trust in low electro-magnetic emissions, high immunity to external fields, and robust, industrial-grade performance with high noise immunity, with a temperature operating range of up to 125 oC.

With utilitarian and highly integrated safety features, Skyworks defined the industry standard for isolated gate drivers—high-side, low-side, and dual. In addition to each of the benefits of our proprietary CMOS capacitive isolation technology, which include signature low electro-magnetic emissions, high immunity to external fields, and robust industrial grade performance, Skyworks’ gate drivers also include several safety-integrated features: dead-time programmability, overlap protection, power status pin positioned on the isolated side, and asynchronous shutdown protection.

Skyworks Si890x/Si892x isolated analog and isolated ADCs are ideal for a broad range of applications, including AC-DC switching power supplies, isolated DC-DC supplies, UPS systems and inverters for motor control. The Si890x enables isolated AC mains monitoring while the Si892x provides shunt resistor-based current sensing solutions for a wide range of power applications.

Skyworks offers a complete set of I/O solutions for the industrial automation market. The Si838x isolated bipolar digital input offers eight sourcing or sinking channels in a compact package. This is ideally suited for a wide range of industrial voltage levels including the IEC 61131-2 standard of 24 V. The Si834x Isolated Smart Switch combines four low RON high-side or low-side switches with robust diagnostics and channel protection. The Si875x Isolated FET driver offers a simple method for customers to replace solid-state relays (SSRs) or electromechanical relays (EMRs) with a compact device requiring only one power supply. Flexible outputs support driving AC or DC load configurations. All industrial I/O products include Skyworks cutting-edge safety- rated isolation qualifications certified by UL, CSA, VDE and CQC.

Skyworks' IEEE-compliant PoE powered devices (PD device) and PoE PSE (power sourcing equipment) simplify design, reduce BOM and speed time to market for industrial and communications applications.
