HCPL-061N#500 Application Field and Working Principle

Optoisolators - Logic Output are components designed specifically for applications that require electrical isolation between input and output, resulting in improved operational safety. The optoisolator has numerous advantages and applications, and the HCPL-061N#500 serves as an example of a logic output optoisolator. The boundaries and capabilities of this particular optoisolator can be explored to understand how it functions and where it can bring benefit.

Application Field

The HCPL-061N#500 is suitable for controlling logic circuits when connecting a PNP phototransistor and a built-in reverse parallel Darlington array in combination. This optoisolator is generally suitable for communication and control applications in consumer and industrial electronics.
The HCPL-061N#500 can be used for operating logic gates, control circuits, board monitoring systems, monitoring of DC/DC converters, circuit protection systems and automatic assembly lines.

Features

The optoisolator uses a hybrid process and incorporates an LED as optical interrupter or a phototransistor as switches in the same package. The HCPL-061N#500 features an 4N35 type photo transistor as the optocoupler inside its package. The Schottky barrier on the light-receiving surface reduces the forward voltage drop, reducing switching time. Besides, the low capacitance also reduces the power consumption over the application range compared to earlier logic output optoisolators.

The optoisolator also has an isolation voltage in excess of 5000Vrms/Vdc to protect the device from electrical interference. This high isolation voltage improves the reliability of the optoisolator and ensures device safety. Furthermore, low leakage current reduces the power loss in the system.

Working Principle

When the LED in the HCPL-061N#500 is energized, it emits light of a specific wavelength. This light exits the LED and enters the optocoupler (positioned on the other side of the optoisolator package), where it is absorbed by a phototransistor. The phototransistor then emits photocurrent, which results in a voltage change in the phototransistor. The voltage change thus created produces a logic signal in the form of High/Low levels.

The LED and the phototransistor are electrically separated and connected to each other through the light. The electrical circuit is formed through optical (photon) energy. As electricity, light can travel only in a straight line and cannot be curved, so the LED and the phototransistor are designed to be physically located in the same package to allow the light to directly pass from one component to the other.

Conclusion

Optoisolators - Logic Output are designed to protect communications and control lines in diverse applications. The HCPL-061N#500 is a solid example of this category, offering a hybrid process, reverse parallel Darlington array, Schottky barrier, and a 5000Vrms/Vdc isolation voltage. The working principle relies on a light emitter and a phototransistor working in tandem, forming what is essentially a circuit through photon energy.
