Working Principles

The ACPL-7970-000E optocoupler utilizes an infrared LED and a photodetector to achieve electrical isolation. When an input signal is applied to the VIN pin, the LED emits light, which is then detected by the photodetector on the output side. This optical coupling ensures that there is no direct electrical connection between the input and output circuits, providing galvanic isolation.
