Introduction

The Si88xx integrates Skyworks’ proven digital isolator technology with an on-chip isolated dc-dc converter that provides regulated output voltages of 3.3 or 5.0 V (or >5 V with external components) at peak output power levels of up to 5 W. These devices provide up to four digital channels. The dc-dc converter has user-adjustable frequency for minimizing emissions, a soft-start function for safety, a shut-down option and loop compensation. The device requires only minimal passive components and a miniature transformer. The ultra-low-power digital isolation channels offer substantial data rate, propagation delay, size and reliability advantages over legacy isolation technologies. Data rates up to 100 Mbps max are supported, and all devices achieve propagation delays of only 23 ns max. Ordering options include a choice of dc-dc converter features, isolation channel configurations and a failsafe mode. All products are certified by UL, CSA, VDE, and CQC. Automotive Grade is available for certain part numbers. These products are built using automotive-specific flows at all steps in the manufacturing process to ensure the robustness and low defectivity required for automotive applications.
