OPIC™ Series, Special Purpose Isolators

Special purpose isolators are specialized electronic circuits that utilize one or two channels of optoelectronic components to perform specific tasks in various applications. These isolators are designed to meet the specific requirements of different tasks, providing enhanced functionality and performance. One common application of special purpose isolators is as I2C repeaters. They facilitate the extension of I2C bus communication over longer distances by amplifying and regenerating the signals. This allows for reliable data transmission between devices connected to the I2C bus. Line receivers are another type of special purpose isolators that are used to receive signals from long transmission lines, such as telecommunication lines or industrial networks. These isolators ensure signal integrity and provide protection against noise and voltage fluctuations. Current loop receivers and transmitters are special purpose isolators used in industrial control systems where analog signals are transmitted over long distances. They convert the analog signals to current loops for robust transmission and isolation. Optical power converters are isolators that convert electrical power to optical power or vice versa. They are commonly used in fiber optic communication systems, enabling the transmission of data over long distances with minimal loss. Photocell optocouplers are special purpose isolators that use a combination of a photodiode and a phototransistor to provide electrical isolation and signal transfer. They are often employed in applications where precise control and monitoring of light levels are required, such as in automatic light sensors or feedback systems. Power MOSFETs and power transistor drivers are special purpose isolators used to control high-power devices such as motors or switches. They provide electrical isolation between the control circuitry and the power components, ensuring safe and efficient operation. Special purpose isolators come in different mounting types, including surface mount, through-hole, and free-hanging options. This allows for flexible installation and integration into various systems. When selecting special purpose isolators, voltage supply and output current are important differentiation parameters to consider. The voltage supply specification indicates the range of input voltage that the isolator can operate with, while the output current specification determines the maximum current that the isolator can handle. In summary, special purpose isolators are optoelectronic circuits designed to perform specific tasks in various applications. They include I2C repeaters, line receivers, current loop receivers and transmitters, optical power converters, photocell optocouplers, power MOSFETs, and power transistor drivers. Special purpose isolators come in different mounting types and have differentiation parameters such as voltage supply and output current. They provide enhanced functionality, isolation, and performance for specific application requirements.
