Optoisolators are designed to provide electrical isolation between two circuits, while transmitting an electrical signal from one circuit to another. FOD8163TR2, belonging to optoisolator category ‘logic output’, is an integrated circuit designed to transfer digital information between two circuits. The output of this device is capable of sourcing and sinking current when available. It can protect electronic systems against customer induced transients, common mode noise, overloads and power surges. This article will provide information about application field and working principle of FOD8163TR2.

Application field and Usability of FOD8163TR2

FOD8163TR2, optimally designed optoisolator, is highly useful for industrial applications. It is used to provide transient protection and immunity between two circuits that are connected electrically. It is also used in motor control systems, motion controllers, power conditioning systems, communication systems, display backlighting systems and medium sized systems. It comes enclosed in a small 8-pin DIP package, is very easy to install and provides high performance within a wide operating temperature range. This opto-isolator is suitable for transmitting high frequency signals up to 10MHz with error-free data transmission. The most interesting feature of FOD8163TR2 is its high reliability.

Working Principle of FOD8163TR2

Optoisolators consist of an LED and a phototransistor, which are placed in an optically isolated package. This optoisolator is designed with an optocoupler, and the internal LED is modulated with a signal. The resulting pulse modulated light is received by a phototransistor which is also placed inside the device. FOD8163TR2 is designed with an internal resistor for LED current limitation that is determined by the particular voltage range. When the LED is activated, current passes through it and the phototransistor is turned on, triggering the flow of current. The logic ‘Low’ state ion LED can be selected from two ranges, 10mA or 20mA. t can either source or sink the current, depending on the input signal. The power consumption of this opto-isolator, when it is active, is quite low, making it feasible for use in many different applications.

Apart from these, FOD8163TR2 also has the capability to electrically isolate two circuits through recognition of very small signals. It can send and receive signals over vast range of magnitudes. This opto-isolator has the ability to recognize frequency variations, shifts due to line noises and undesired interference. These features make the use of FOD8163TR2 quite practical and convenient.

Conclusion

To conclude, FOD8163TR2 optoisolator is an important device, designed specifically to transfer digital information between two circuits. It is used to provide electrical isolation between adjacent circuits and is suitable for transmitting high frequency signals up to 10MHz. It has the capability to recognize frequency variations, shifts due to line noises and undesired interference. This optoisolator is highly recommended for use in industrial applications as it is a reliable and cost effective solution.
