Optoisolators are electrical isolator components that are used to provide galvanic isolation between two circuits. FODM8071R2 is one type of optoisolator from Avago Technologies, which is a Logic Output type. This optoisolator has many applications and its working principle will be detailed in this article.

1. Introduction

The FODM8071R2 is an optoisolator which is also known as an optocoupler or a type of photocoupler, and is used to transfer electrical signals between two different circuits, that are of different potentials. This is done by providing galvanic isolation between two different circuits without the need for direct electrical contact between them. The FODM8071R2 converts very small electrical signals from one circuit to an optical signal and back, thus providing electrical isolation between the two circuits. This allows the two circuits to communicate without affecting the other circuit’s operation and without creating a path for current to the other circuit.

2. Applications

The FODM8071R2 has a wide range of applications in many different industries and types of equipment. Some of the most common applications are in microcontrollers, medical systems, automotive systems, inverters, telecommunications, and instrumentation systems. It can be used to convert low-level logic signals from one circuit to a higher-level signal suitable for use in another circuit. It can also be used to reject noise from one circuit while transferring signals to another and to provide safety isolation in dangerous applications.

3. Working principle

The FODM8071R2 works by converting small electrical signals from one circuit to optical signals and back. It consists of two parts, an LED and a photodetector. The LED is the light source and the photodetector is the receiver. The LED will produce light when an electrical signal is present. This light is then picked up by the photodetector, which converts the light signal back into an electrical signal. This electrical signal can then be used by the other circuit.

The FODM8071R2 also includes a photovoltaic element which provides protection for the LED. This element keeps the LED from over-powering the photodetector, and therefore provides more reliable isolation. This is especially important in applications where the accuracy of the signal transfer is critical.

4. Benefits

The main benefit of FODM8071R2 is its ability to provide galvanic isolation between two circuits. This means that there is no direct electrical contact between the two circuits, and therefore there is no danger of electrocution or short circuits. Additionally, it can provide a high degree of insulation between the two circuits, allowing them to communicate without affecting the other circuit’s operation. It also helps to reject noise from one circuit and can provide protection in dangerous applications where high voltage is present. Additionally, the FODM8071R2 is a very reliable and efficient component, making it suitable for a variety of applications.

5. Summary

The FODM8071R2 is an optoisolator component from Avago Technologies, and is a Logic Output type. It is used to provide galvanic isolation between two different circuits without the need for direct electrical contact between them. This is achieved by converting electrical signals to optical signals and back, which allows the two circuits to communicate without affecting the other circuit’s operation. The FODM8071R2 can also provide protection in dangerous applications where high voltage is present and is suitable for a wide range of applications in many industries. It also has the benefit of being a very reliable and efficient component.
