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 kV RMS
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.
