8102805PA Optoisolators - Logic Output Application Field and Working Principle
Introduction
Optoisolators, also known as optical couplers or optocouplers are input-output integrated optical devices which work by transmitting signals between two circuits of electrical systems that are electrically isolated from each other. The 8102805PA is an optoisolator which is specifically designed for applications in the field of logic output and logic input. It has a unique set of features and functionalities which make it a superior choice for the engineers and system designers. In this paper, we will discuss the application field and the working principle of the 8102805PA optoisolator.Application Field
The 8102805PA optoisolator is designed to be used in logic control applications, including timing/counter, motor/solenoid driving, digital switching, and sensor/transducer interface. It is used to provide isolation between the controlling system and the responding system.It is often used in automotive applications as it offers high-speed switching with high isolation voltage, and is capable of providing switchable current of up to 30mA. It can also be utilized in the aerospace, medical, and telecommunications industries as it offers low-power consumption and superior shock and vibration (Vibration and Shock) resistant features, making it suitable for applications which need to operate under extreme conditions.Working Principle
The 8102805PA optoisolator utilizes a custom-integrated vertical cavity surface emitting laser (VCSEL) which emits infrared light when excitation voltage is applied to it. The transmitted infrared light is then received back with a photodiode, which is then connected to the input node of the optoisolator. This results in current flow between the collector and emitter of the optoisolator.The collector-emitter of the optoisolator acts as a controlled switch, turning on and off in response to the input signal. This allows for the isolation of the output from the input signals. The 8102805PA optoisolator also has an open collector output which allows for a high output voltage which can be used for digital logic switching.Conclusion
The 8102805PA is an optoisolator which is specifically designed for applications in the field of logic output and logic input. It is designed to be used in logic control applications, including timing/counter, motor/solenoid driving, digital switching, and sensor/transducer interface. It utilizes a VCSEL and a photodiode which, when working together, create an isolation barrier between the input signal and the output. The 8102805PA optoisolator also has an open collector output which allows for a high output voltage which can be used for digital logic switching.The specific data is subject to PDF, and the above content is for reference
