Key Takeaways

• Skyworks has launched the Si86Px family of digital isolators that integrate high-performance isolation with a DC-DC converter.
• The Si86Px significantly reduces design complexity, PCB area, and BOM count for industrial and automotive applications.
• Key features include industry-leading load regulation, high data rates up to 150 Mbps, and robust performance in harsh environments.

Innovative Isolation Solution from Skyworks

Skyworks has introduced the Si86Px family of digital isolators, a cutting-edge solution that fuses high-performance digital isolation with an integrated isolated DC-DC converter and miniature transformer. This product is tailored for industrial and automotive electronics and aims to streamline the design of isolated systems, minimizing the required PCB space and components while simplifying overall design processes.

The Si86Px addresses a crucial challenge faced by system designers: creating high-quality isolated power where board space is limited or where an isolated power source is unavailable. By consolidating signal and power isolation into a single package, the Si86Px accelerates time-to-market while providing a stable and regulated power source for sensitive components like ADCs and sensors.

Yusuf Jamal, Senior Vice President and General Manager of Skyworks’ RF and Mixed-Signal Intelligence Solutions business, states, “At a time when industrial designs demand higher performance in smaller footprints, the Si86Px delivers a complete, easy-to-use isolation subsystem. By integrating power and signal isolation with industry-leading load regulation, designers can simplify their designs without compromising performance.”

Advanced Integration for Efficient Design

The Si86Px family utilizes Skyworks’ digital isolator technology, incorporating an isolated DC-DC converter that can supply up to 0.5 W of isolated power. This eliminates the need for bulky external transformers and power modules, leading to more compact and cost-effective system designs. Notable advantages of the Si86Px include:

• Industry-leading Load Regulation: Achieving a remarkable 0.1 percent typical regulation for powering sensitive ADCs and sensors.
• High Data Rate Capability: Supporting data rates up to 150 Mbps, facilitating swift industrial communication via protocols like SPI and RS-485.
• Common-Mode Transient Immunity: With 100 kV/µs immunity, it ensures reliable data integrity in noisy environments, such as those encountered in motor drives.
• Compact Packaging: Housed in a WB SOIC-16/20 package, this design simplifies manufacturing and optimizes space usage.

Designed for Harsh Environments

The Si86Px is engineered for demanding industrial and automotive applications, functioning effectively in temperatures ranging from –40°C to +125°C while providing 3.75 kVrms isolation. It is ideal for industrial automation and factory equipment, meeting the needs of environments where reliability and performance are paramount.

The integrated power architecture and low-EMI design further simplify system designs, allowing developers to meet performance and compliance standards with reduced external components. Notably, the Si86Px boasts significantly tighter load regulation compared to comparable integrated power isolators, offering up to 10 times better regulation for sensitive analog components.

With faster data rates that exceed 100 Mbps, the Si86Px ensures enhanced control and responsiveness within system designs, making it a pivotal addition in modern electronics.

The Si86Px family is now available for purchase, marking an exciting development for engineers and designers in need of effective digital isolation solutions.
