Digital Isolators

Digital isolators use digital signals to connect two parts that must be electrically insulated from each other. For example, a digital isolator might be used to protect a computer control system from electrical interference or fluctuations of a motor or power supply system. In this article, we will look at the IL716-3E digital isolator, its application fields, and its working principle.

Application Fields

The IL716-3E is a programmable, high-speed, full-isolated single-channel digital isolator. It has a maximum data rate of 4 Mbps, a transmission distance of 1000 m, and a wide temperature range of -25~85°C. It is used in a wide range of applications, including:

• Power supply isolation for industrial control systems, LED lighting systems, automotive chargers, solar panels, wind power converters, etc.
• Data transmission for industrial digital systems, wireless remote control systems, automotive control systems, powerline communication systems, and more.
• Electrical isolation for medical systems, military systems, electrical energy metering systems, power protection systems, and other systems requiring electrical isolation.

Working Principle

The IL716-3E digital isolator operates on a principle called “digital pulse-width modulation”. In this type of transmission technology, the transmission of data from one unit to another takes place through a special set of digital signals, rather than through traditional analog signals. This is accomplished by encoding every bit of data as a digital signal (a square wave) and sending it across the isolator. The length of time the digital signal is “on” or “off” corresponds to the amplitude of the input signal—the taller the peak of the digital signal, the more time it is “on”.

The IL716-3E digital isolator is also equipped with a series of advanced features to further improve performance. For instance, it features automatic power-on reset circuit that can automatically reset both the isolated unit and the non-isolated unit after power-on, and an automatic fault-detecting circuit that can detect and report any transmission errors or issues. Additionally, the IL716-3E has a wide supply voltage range, which allows it to be used in a variety of applications.

Conclusion

The IL716-3E is a versatile digital isolator that can be used in various applications, from industrial control systems to medical systems. It operates on a digital pulse-width modulation principle, which ensures reliable data transmission over long distances. Furthermore, its wide supply voltage range allows it to be used in a variety of different applications. All these features make the IL716-3E an ideal choice for applications requiring digital isolation.
