Digital Isolators -- ADUM1223BRWZ-RL Application Field and Working Principle

Digital isolators are electronic components used to prevent electrical current from interfering between two circuits that are electrically isolated but connected by a physical link. Digital isolators, also known as optocouplers, are widely used in digital and analog circuit designs. One digital isolator of particular note is the Analog Devices ADUM1223BRWZ-RL. This isolated gate driver IC is designed for applications which require high electrical isolation and high signal bandwidth.

Applications

The ADUM1223BRWZ-RL’s applications include automation systems, factory automation, motor control, medical equipment, and instrumentation systems. It features a typical isolation voltage of 5 kVrms, a supply voltage of 4.5 to 20 VDC, and a high output current of up to 200 mA. This isolated gate driver IC is also bidirectional, meaning it can receive a signal in either polarity. The signal can be oriented according to the user’s needs with the click of a button.

Working Principle

The working principle behind the digital isolator ADUM1223BRWZ-RL is based on optical coupling. An optical coupler is a type of solid state device that interrupts the flow of electricity between two points. It functions by means of an LED which sends a beam of light to a photodetector. This photodetector picks up the optical signal and sends a corresponding electrical signal to the receiving end. The electrical isolator then blocks the flow of electricity from the transmitting to the receiving end. This optical coupling method allows the ADUM1223BRWZ-RL to provide a high level of electrical isolation. With this IC, the user can operate digital signals with complete insulating protection from the power source. This prevents noise and interference from entering the system and ensures the highest degree of reliability.

Conclusion

The ADUM1223BRWZ-RL digital isolator is a great example of how optical coupling technology can be used to provide a high degree of electrical isolation. The high isolation voltage and output current makes this IC suitable for a wide range of industrial and medical applications. Its bidirectional nature allows the user to tailor the signal to his or her application with ease. Overall, Analog Devices’ ADUM1223BRWZ-RL digital isolator is a great choice for applications requiring high performance galvanic isolation. With its high isolation voltage and output current, this IC is ideal for a variety of industries. The optical coupling technology which it utilizes makes it a reliable option for isolating digital signals and keeping them protected from external interference.
