Introduction
Optoisolators, also known as optocouplers or photocouplers, are amazing electronic components that allow electrical isolation between two circuits by using light as the medium. Among various types of optoisolators, logic output optoisolators, such as PS9821-2-F4-AX, are most commonly used in digital control applications and have become popular solutions for providing electrical isolation when passing control signals and voltage control.Application field and Working Principle
The PS9821-2-F4-AX optoisolator is designed to be used for logic voltage translation between different circuits, meaning that it isolates the power between two digital circuits while allowing communication between them. It is a two-channel, low-input current optoisolator capable of controlling and providing the necessary electrical isolation between circuits. Its compact design makes it perfect for all types of space-constrained applications.The primary component of PS9821-2-F4-AX is an infrared light-emitting diode (IRED). This diode transmits a beam of light across a gap between two circuits. On the opposite side, a photosensitive transistor is placed, which acts as the receiver for the beam. When voltage is applied to the input optoisolator, the infrared LED is enabled and generates a beam of light to the receiver component. This transistor then amplifies the signal, recreating the original signal on the opposite side of the gap.The product is also designed with two storable resistors for gate control and a reverse current protection function for the LED. The resistors provide a safety margin for the LED, ensuring that the IC does not overheat. The reverse current protection function prevents current from flowing backwards from the output to the input, ensuring that the circuit remains safe.Applications and Advantages
The PS9821-2-F4-AX optoisolator is perfect for low-input current applications, which require the isolation of power or logic voltage between two circuits. It is mainly used in interfacing logic circuits, such as TTL to CMOS. Additionally, the PS9821-2-F4-AX can be used for data transmission and signal isolation in industrial and commercial control systems, such as automotive control systems, electronic keyboards, measuring instruments, and more.The most notable advantage of the PS9821-2-F4-AX optoisolator is its small size which allows it to be used in a variety of space-constrained applications. Additionally, PS9821-2-F4-AX is a high-quality, low-cost optoisolator that provides reliable electrical isolation and signal transmission between two circuits. The design also includes two storable resistors for gate control and LED reverse current protection functions, which provides additional safety features to the circuit.Conclusion
The PS9821-2-F4-AX optoisolator is widely used for providing electrical isolation between circuits, as it reliably and accurately transmits data and signals between circuits. It is designed for low-input current applications, and its small size makes it perfect for a variety of space-constrained applications. Additionally, the product offers two storable resistors for gate control and LED reverse current protection to ensure the safety of the circuit.The specific data is subject to PDF, and the above content is for reference
