Application Field and Working Principle

The PI8642BB-B-IS1R digital isolator offers excellent performance in industrial applications, medical applications, automotive systems and power electronics. It is ideal for use in isolation and signal conversion applications in which it is necessary to protect sensitive components from noise, interference or over voltage. The optical design of the PI8642BB-B-IS1R uses photovoltaic isolation technology in order to isolate two separate circuits, allowing different voltages to be transmitted between the two isolated circuits without interference.

The main principle of the PI8642BB-B-IS1R digital isolator is to use an optically isolated device to transfer signals between two circuits with different impedances. The optical isolator uses an input conditioning circuit to generate a stable current signal, which is then transferred across two optical port interfaces. The optical energy is then converted to electrical energy and the signals are transmitted to two circuits, electrically isolated from each other. By using optically isolated communication between the two circuits, any noises due to interference or overvoltage can be eliminated.
