Optoisolators - Logic Output

Optoisolators are devices used to transfer an electrical signal through an isolation barrier, providing both protection and noise immunity for the signal path. An optoisolator consists of an LED or infra-red diode, which is used to detect the electrical signal and create an output signal in the form of light; and a photodiode or photo transistor, which is used to convert the light signal back into an electrical signal. HCPL-1930 is an opto logic output optoisolator which is designed specifically for use in digital logic chips, microprocessors, and related applications. In this article, we will discuss the application field and working principle of the HCPL-1930.

Application Field of HCPL-1930

The HCPL-1930 optoisolator is specifically designed to power digital logic circuits. The optoisolator has a logic input and photodiode output, and is used in many applications such as isolating microprocessors, power supplies, and analog circuits from each other. The HCPL-1930 also offers low current operation, fast switching speeds, and high input-to-output photon isolation.

Other applications for the HCPL-1930 optoisolator include data transfer and communication, including primary side and secondary side connectors, and embedded and remote control systems. The HCPL-1930 is also ideal for detecting low voltage and load current in high reliability systems, protecting against over-current and under-current conditions, and power-up sequencing.

Working Principle of HCPL-1930

The combination of LED or infrared emitter and photodiode is at the heart of the HCPL-1930 optoisolator. When the input voltage is applied to the LED emitter, the device emits a visible or infra-red light signal, which is then detected by the photodiode. The photodiode then converts the light signal into an electrical signal, which is then passed on to the output circuit.

The HCPL-1930 is designed to perform the two-stage conversion from the input voltage to output voltage, with very low current across the isolation barrier. The optoisolator\'s low-noise design enables the device to transfer digital signals with very low power loss, and its low voltage-drop operation allows the device to function properly at low voltage levels when compared to other optoisolators.

The HCPL-1930 also offers several features that make it ideal for digital logic applications. Its fast switching speeds allow for high-speed signals to be passed, while its high input-to-output photon isolation makes the device extremely reliable for embedded and remote control systems.

Conclusion

The HCPL-1930 optoisolator is a versatile and reliable device that is designed specifically for powering digital logic circuits. The optoisolator provides both protection and noise immunity for digital signals, and offers several features that make it ideal for applications such as data transfer, communication, and embedded and remote control systems. It is also ideal for protecting against over-current and under-current conditions and for power-up sequencing. With its fast switching speeds and high input-to-output photon isolation, the HCPL-1930 optoisolator can be used in a variety of applications with high reliability.
