Optoisolators are components that electrically and optically isolated an electrical signal to provide a feedback loop. They can be found in many industrial applications and are used extensively in the automotive industry. One of the most common optoisolators is the ACPL-1772L Transistor, Photovoltaic Output Optoisolator, which offers excellent electrical characteristics and high-level reliability in a single package.

Application Field

The ACPL-1772L is designed for many applications and can be used in virtually any environment. It can be used as an in-line signal isolation device for protection against electrical shock hazards, as an input buffer for isolated control systems, as an interface between isolated circuits, and as an output receiver for isolated communication systems. It is also suitable for use in high temperature, humidity, and vibration environments.

The ACPL-1772L is designed for use in applications where low power consumption is important, such as battery operated applications. It is also ideal for low noise applications, with a low output noise voltage of 0.05mVrms and low input currents of 5mA. Its high level isolation makes it ideal for applications where isolation between control and the controlled circuits are required.

Working Principle

The ACPL-1772L is a photovoltaic output optoisolator. This means that it uses light as a medium to transfer an electrical signal from one side of the device to the other. In this particular optoisolator, the input signal is provided to the LED on the input side of the device. The input signal is then converted to light which is directed to the photodiode on the output side of the device. The photodiode then converts the light back to an electrical signal which is then used as the output signal, isolated from the input signal.

The ACPL-1772L is a single package optoisolator, which means that the LED and photodiode are both in the same package. This allows for higher levels of integration and is ideal for applications where space is limited. The ACPL-1772L also features a wide range of transimpedance levels, from 75Ω to 350Ω. This allows for a wider range of input signals to be used, from low level to high level signals.

Conclusion

The ACPL-1772L Transistor, Photovoltaic Output Optoisolator is an excellent choice for applications where signal isolation and low power consumption is required. It features a wide range of transimpedance levels, an integrated LED/photodiode, and high-level isolation. The ACPL-1772L is suitable for use in a variety of applications, including automated control systems, isolated communications, and power management systems.
