Optoisolators are used to provide electrical isolation between input and output lines of a circuit, to prevent failure due to transients induced in the lines. They have become a standard feature in many circuits in recent years, including in commercial applications. Such isolation is essential for many applications that require high reliability and also for safety reasons. One popular optoisolator product is the FOD0710R2, which offers a common-cathode output type, logic output, and extremely good isolation between input and output.

Applications of the FOD0710R2

The FOD0710R2 optoisolator is designed for use in manually operated circuits, such as those used in the control of industrial equipment, medical instruments, aviation and aerospace systems, and security systems. The FOD0710R2 is designed to be used either in single or dual-channel configurations, allowing for the rapid connection of two isolated circuits. It is also used where either the input or output device requires a logic level, ensuring the circuit integrity is maintained no matter how the logic levels vary.

Working Principle of the FOD0710R2

The FOD0710R2 utilizes a GaAlAs infrared emitting diode, which emits an infrared beam that is converted into an electrical signal by a phototransistor. The emitted beam passes through an insulated gap and is detected by the phototransistor, effectively creating an electrical connection between the two circuits. The optoisolator takes the junction voltage of the phototransistor into consideration, and it then amplifies the difference between the logic inputs and the output voltage in a current mirror amplifier. The result is a low-power and high-reliability connection between two isolated circuits.

Benefits of the FOD0710R2

The FOD0710R2 offers a number of benefits, one of which is that it has very low power consumption. This means that it can be used in low-power applications, reducing the overall energy consumption of the circuit. It is also incredibly reliable and robust, due to its insulation – ensuring that the circuit remains isolated even in the event of high voltage transients. The FOD0710R2 also offers a very fast switching time, making it a suitable choice for fast-paced applications. It can also be used to link logic devices, making it a versatile choice for many circuits.

Summary

The FOD0710R2 optoisolator is a high-reliability solution for providing electrical insulation between two separate circuits. It offers various benefits, such as low power consumption, fast switching time and the ability to link logic devices. As a result, the FOD0710R2 is ideal for applications that require a reliable solution for electrically isolating two circuits, such as in industrial and medical devices.
