Optoisolators are devices that use a combination of light emitting diodes (LEDs) and transistors to transfer electric power between two isolated areas. The VOS617A-2T is a type of opto-isolator that uses a photovoltaic output rather than a transistor. This device is an extremely useful component in various digital and analog circuits, providing isolation from hazardous high voltage.

Application Field

The VOS617A-2T opto-isolator has multiple applications in the automotive, industrial and consumer markets. Its applications include voltage and current regulation, signal conditioning, isolation of power supplies and as an interface between digital and analog circuits. It can also be used in high speed communication lines such as CAN, ethernet and usb devices. This device is particularly useful in applications that require a high degree of electrical isolation between two systems.

Working Principle

The VOS617A-2T opto-isolator operates in two stages. In the first stage, the LED is illuminated, producing a current that flows through the photovoltaic diode. This current is used to generate a voltage between two outputs, one on the input side and the other on the output side. On the output side, the voltage is then used to drive a transistor which switches the device’s output.

When operated in a complementary mode, the transistor is used to activate an additional state in which a resulting load current can be controlled. This principle offers the ability to precisely control the output current to the load without compromising system isolation. This makes the VOS617A-2T a great choice for applications that require a high degree of electrical isolation and precise control.

Conclusion

The VOS617A-2T opto-isolator is a versatile device that is commonly used in various automotive, industrial and consumer electronics applications. It is capable of providing a high degree of electrical isolation while providing a precise regulation of output current. Its photovoltaic output is capable of providing a high degree of system isolation, and its two-stage operation allows for a precise control of the output current.
