Description

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 Silicon Laboratories' 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-to-

part matching, and superior common-mode rejection compared to opto-

isolated 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.
