Introduction

Optoisolators - Logic Output are optically linked isolators designed to provide electrical isolation of high speed logic signals, such as address and data busses, transceiver interfaces, etc. The HCPL-7601#500 from Avago is representative of such a component, and is designed for use in 5V logic systems. In this article we will discuss its application field and operating principle.

Application Field

The HCPL-7601#500 is a versatile component designed for a number of different application fields. It features a GaAs LED light source, which enables fast-switching signal transmission. The HCPL-7601#500 is also designed to provide high-impedance input signals in order to reduce ground loop noise, thus making it suitable for use in digital systems requiring high noise immunity. It is particularly useful for applications that require high-frequency pulse isolation or signal isolation over long distance cables. It can be used as a monitoring device in a distributed system to detect an array of logic state changes. Similarly, it can be used in motor control applications, as it can provide low latency isolation of motor-control signals over wide frequency band transmissions.

Working Principle

When plugged into its socket, the HCPL-7601#500 acts as an optically coupled-gate. The input signal is routed through the emitter which is connected to the LED. The LED then emits a light which is in turn received by the detector. When the light from the LED reaches the detector, it causes a flow imbalanced current to build up and triggers the output signal. This output is routed through the output stage which then sends it to the user-specified target. The LED that is employed in the HCPL-7601#500 is easily adjustable, making it possible to achieve high-frequency operation. Additionally, the detector features various protection mechanisms to protect it from damage or overload. These safeguards include a voltage limit of 40V and a reverse voltage limitation.

Conclusion

In conclusion, the HCPL-7601#500 is a versatile component which is suitable for many different types of applications. It can provide high-speed signal transmission, and also offer protection from overloads and other damage. Furthermore, its adjustable LED technology allows for high-frequency operation. In summary, the HCPL-7601#500 offers many advantages, and is a great choice for applications which require Isolation Optocouplers.
