ACPL-P484-000E Application Field and Working Principle

ACPL-P484-000E is an optoisolator logic output device which is most commonly used in industrial applications. This type of optoisolator is used to provide isolation between input and output circuits. It’s most typically used in power applications and power controlling applications, particularly in automotive and industrial applications.

Optoisolators - Overview & Working Principle

Optoisolators are solid-state isolators that provide electrical isolation between two or more circuits without physical contact. They work by passing an electrical signal across an optical border created by light-emitting diode (LED) and a light detector. The electrical signal of one circuit will be converted to light energy and optically transmitted, while the light energy of the other circuit will be converted to electrical signal and optically transmitted. The optical signals contain no electrical potential, so there is no danger of short circuits.

The ACPL-P484-000E optoisolator from Avago Technologies uses an AlGaAs LED to emit a specific frequency of light that is then detected by a light detector. The light detector is typically a phototransistor or optical isolator IC. The most common application for this optoisolator is providing isolation between low voltage and higher voltage circuits, such as between the 12V power line and the control circuits of an automobile. This type of optoisolator can also be used to provide isolation between analog and digital circuits, and between circuits connected to noisy environments.
