Working Principles

The HCPL-7510 is an optocoupler that utilizes an infrared LED and a phototransistor to provide electrical isolation between input and output circuits. When the input current flows through the LED, it emits infrared light, which is then detected by the phototransistor. The phototransistor's output current is proportional to the intensity of the received light, allowing for signal transfer between different voltage levels.
