Introduction

Optoisolators are electrical isolation components which use a light source and a detector to isolate low power electrical signals. Optoisolators are divided into Logic Output, Analog and Triac Output categories. Among them, Logic Output optoisolators are the most common kind which employ LEDs as the light source to couple isolated digital signals.HCPL-263L-320E is an example of a Logic Output optoisolator.

Application Field

The HCPL-263L-320E is designed for applications where signal isolation and noise immunity are essential. It can be used in solar energy systems, telecommunication systems, industrial systems and DC motor controllers.

Solar Energy Systems

Solar energy systems are widely used in applications such as residential and commercial buildings, communications infrastructure and transportation. An important aspect in such systems is ensuring that the energy output is consistent and reliable. The HCPL-263L-320E is an ideal component for such applications since it can isolate signals, increase the noise immunity and ensure a consistent energy output.

Telecommunication Systems

In telecommunication systems, there are many signals that must be isolated which includes various data and control signals. The HCPL-263L-320E provides an efficient way to isolate signals and protect system performance from electrical noise.

Industrial Systems

Industrial systems often require significant noise isolation to ensure reliable performance. The HCPL-263L-320E can effectively isolate signals in such a way that it suppresses signal noise and supports a robust signal output.

DC Motor Controllers

DC motor controllers require a high level of noise isolation to ensure reliable performance. The HCPL-263L-320E can efficiently isolate signals and provide the desired noise immunity.

Working Principle

The HCPL-263L-320E utilizes a combination of an LED and a photodetector to achieve isolation. The LED is driven by an internal bipolar transistor, with the input voltage being supplied to the base of the transistor. The transistor then drives the LED which emits light when it is turned on. On the other side, the output of the optoisolator is the detect photodetector which converts the light emitted by the LED to an electrical current. In this way, the HCPL-263L-320E can isolate signals without affecting the output signal quality. The HCPL-263L–320E can also provide transient protection. When an external surge is experience, the zener diode on the output side of the detector is triggered and ensures that the output signal remains unaffected from any noise. The HCPL-263L–320E also provides ESD protection which is enabled by an internal transistor structure and ensures that the output signals remain consistent despite ESD surges.

Conclusion

The HCPL-263L-320E from AVAGO is an ideal choice for applications which require noise isolation and reliable performance. It utilizes a combination of LEDs and photodetectors to provide signal isolation and also provide transient and ESD protection to ensure that the output signals remain unaffected by noise. The HCPL-263L-320E can be used in solar energy systems, telecommunication systems, industrial systems and DC motor controllers.
