1. Describe

SI8220BB-D-ISR is a high-performance function upgrade for optocouplers Drivers, such as HCPL-3120 and HPCL-0302, provide 2.5 A Peak output current. It utilizes Silicon Laboratories’proprietary silicon Isolation technology, offering 2.5, 3.75 or 5.0 kVRMS options Comply with UL1577 withstand voltage. The technology can achieve higher Compared with optically isolated drivers, it reduces temperature and aging changes, tighter part-to-part matching and excellent common-mode rejection. Although the input circuit imitates a LEDs require less drive current to improve efficiency. The propagation delay time has nothing to do with the input drive current, resulting in Consistently short propagation times, tighter inter-unit differences, and Greater flexibility in input circuit design.
