ACPL-2672L-100

ACPL-2672L-100 is an optoisolator from Avago Technologies. It belongs to the “Optoisolators – Logic Output” category, and is extensively used in a variety of applications due to its range of advantages compared to other optoisolators. This article will discuss ACPL-2672L-100’s application field and its working principle.

Application Field

ACPL-2672L-100 is often used to isolate one section of a circuit from another. This is important in order to eliminate ground loops, minimize system noise, reduce induced signals, and develop voltage/current levels that are different on both sides of the isolator. A variety of devices, such as low-level analog signals, digital signals, mote controllers, and ASICs can all be connected through ACPL-2672L-100.

It is also frequently employed in the industrial environment. Its two insulation barriers give ACPL-2672L-100 a critical advantage over other optoisolators in this sector, particularly when dealing with hazardous, flammable, and extremely high voltage applications. This isolator is also suitable for separating sensitive devices, such as data converters, from high power drivers.

Furthermore, ACPL-2672L-100 is a highly reliable optoisolator, and it is ideal for applications where low-voltage signals have to be switched to higher voltages securely. Applications like optical communications, automotive, medical equipment, and other sectors with stringent safety requirements make extensive use of ACPL-2672L-100.

Working Principle

This optoisolator operates by using the transfer of energy between two regions, through optical waves. The control current and the output voltage are completely isolated from each other. This energy transfer starts off with a chip that contains an LED die, which is situated on the input side. A photodetector receiving element is placed on the output side.

When a positive voltage is applied to the LED die, electricity is generated by the LED, resulting in its forward voltage being dropped. This causes the LED to begin emitting light. The emitted light enters the photo detector\'s diode window, which is then converted into electricity.

The total current that flows through the chip is the sum of the LED\'s control current and the photodetector\'s output current. This current passes through the chip, resulting in an output voltage being generated by the photodetector. This output voltage is then used for various applications, such as controlling relays, converters, and other such devices.

Conclusion

ACPL-2672L-100 is an optoisolator in the “Optoisolators – Logic Output” category, and it offers many advantages over other optoisolators. This isolator finds extensive use in different sectors including industrial, automotive, medical, optical communications, and more. Considering its wide range of applications and reliability, ACPL-2672L-100 is a popular choice for providing electrical insulation.
