Digital Isolators

Digital Isolators are ideal for applications requiring secure conditioning or secure supply of current. The ADN4651BRSZ Isolator is a highly advanced isolator from Analog Devices, Inc., providing secure, galvanic isolation between two points in a digital system. It is used in a variety of applications, from low-voltage to severe industrial, and operates to as high as 5.5 kilovolts.

The ADN4651BRSZ is a four-channel digital isolator featuring a wide operating temperature range of -55 °C to +125 °C. The device is designed to provide a secure conditioning of digital signals between two sides of the network. It does this by isolating the primary and secondary sides of the device which drastically reduces the chances of power disruption or power disturbances that could potentially damage components or systems.

The basic operating principle of the ADN4651BRSZ is the same as any other digital isolator, but with certain automated features that make it a more reliable device. The isolator initially outputs a signal from the primary side, which is then received by the secondary side. The output is further conditioned for improved voltage regulation, better noise performance, and enhanced power efficiency. The unique intelligent sequencing feature of the device enables secure operation under extreme conditions by using a programmable delay period of up to 16ms.

In addition, the ADN4651BRSZ features built-in over-voltage and over-current protection for added safety against unexpected conditions. The built-in over-temperature protection eliminates the need for external cooling systems and provides an additional safety net for the device. It can also detect and diagnose faults remotely, meaning it can be monitored and operated from remote locations. These features make the device suitable for a wide range of industrial applications.

The ADN4651BRSZ digital isolator is particularly well-suited for industrial applications requiring robust and secure signal processing, and is easily integrated into existing systems. Its application fields include motor control, renewable energy, medical component testing, robotics, and automation. The device is highly reliable, with excellent signal integrity and temperature performance even in extreme conditions. It provides maximum protection from short circuits, overloads, and other common problems, making it ideal for tough industrial environments.

The ADN4651BRSZ digital isolator is a robust device designed to provide superior performance and a wide operating temperature range. It is ideal for secure conditioning or securing the supply of current in industrial applications. The built-in features such as intelligent sequencing, over-voltage and over-current protections, and over-temperature protection make it a reliable device for securing digital systems. Its application fields include motor control, renewable energy, medical component testing, robotics, and automation.
