It is often used in industrial automation control systems and responsible for providing electrical isolation between control and output parts in order to reduce grounding hazards and improve system stability. It is also used in power supplies, inverters, converters, circuit breaker and alarm systems, motor drives, signal processing, and many other applications.

It is well suited for operation in high temperature, high shock, and vibration environments. It has the ability to withstand temperatures up to 225°C without losing performance. It is also designed to comply with many safety requirements including UL and IEC requirements.

The ACPL-844-060E is available in a variety of options to cater to the needs of different applications. There are versions available in DIP (dual-inline package) and SSOP (shrouded solderless package).

Working Principle

The ACPL-844-060E optoisolator utilizes a combination of electrical and optical isolation to provide a reliable electrical isolation between two circuits. It contains two monolithic integrated circuits. The first is an optically isolated integrated circuit (OIC), which is a light-emitting diode (LED) emitting light to an input circuit and phototransistor receiving the light. The input circuit allows for a transistorized output.

The second IC is an electrically isolated integrated circuit (EIC), which contains a photovoltaic cell that receives the light from the OIC. The photovoltaic cell is responsible for generating a higher voltage that is used to drive the output circuit. The output circuit provides the required output, which is dependent on the type of input.

The ACPL-844-060E optoisolator provides a reliable means of isolating two circuits. It is a powerful tool for protecting systems against shorts or surges and preventing ground loops. It is also capable of providing insulation up to 1000V RMS (root mean square).

Conclusion

The ACPL-844-060E optoisolator is one of the most reliable and widely used optoisolators in the industry. With its wide range of applications and features, it is no surprise that it has become the standard for electrical isolation. It offers high reliability, a high temperature rating, and safety compliance. Thanks to its combination of optical and electrical isolation, it can provide reliable insulation up to 1000V RMS.
