Digital Isolators

Digital isolators are opto-electronic components specifically designed to isolate one circuit from another or to provide voltage isolation. They are commonly used to ensure that the primary power is isolated from the secondary power by an optically-coupled set of input and output devices. They are widely used in electrical, control and signal circuits to prevent interference from other devices, improve circuit performance, and minimize power losses.

ISO7721DR Application Field and Working Principle

ISO7721DR is a 3.3V digital isolator chip specifically designed to provide high-speed communication between two systems by using optical semiconductor isolation technology. One of its key features is that it has a maximum isolation voltage of 500V, making it suitable for various isolation requirements including industrial control systems. It is also able to provide up to 2A power transfer and up to 2 Mbps data transmission rates. This chip is often used in industrial applications, such as PLC, sensor systems, and instrumentation systems.

The ISO7721DR chip uses a bidirectional cmos circuit composed of a photovoltaic coupler and transistors. The photovoltaic coupler consists of a light-emitting diode (LED) and a photodetector. When the LED receives the input voltage, it emits a light which is detected by the photodetector. This converts the electrical input into optical input, and then creates a voltage signal between the output and input pins of the chip. This voltage signal can then be used by the output circuits to control its operation.

The chip also has several protection features such as Over-Voltage protection (OVP) and Reverse Current protection (RCP). OVP helps prevent damage to the chip due to high voltage input. RCP prevents damage due to reverse current which could otherwise occur in the case of an open-loop circuit.

Overall, the ISO7721DR is a highly reliable and cost-effective digital isolator chip which ensures a safe and reliable communication between two systems. Its operating principle and features make it well suited for industrial applications requiring high-speed communication.
