SI8221DC-D-IS

The Si8220/21 is a high-performance functional upgrade for opto-coupled drivers, such as the HCPL-3120 and the HPCL-0302 providing 2.5 A of peak output current. It utilizes Skyworks Solutions' proprietary silicon isolation technology, which provides a choice of 2.5, 3.75, or 5.0 kVRMS withstand voltages per UL1577. This technology enables higher performance, reduced variation with temperature and age, tighter part-topart matching, and superior common-mode rejection compared to optoisolated drivers. While the input circuit mimics the characteristics of an LED, less drive current is required, resulting in increased efficiency. Propagation delay time is independent of input drive current, resulting in consistently short propagation time, tighter unit-to-unit variation, and greater input circuit design flexibility.
