Digital isolators are electronic components used to reduce or eliminate electromagnetic interference from digital circuits. An isolator is different from an optocoupler in that it takes a digital signal and passes it through a galvanic isolation barrier without changing its output. SI8620BC-B-IS Digital isolator is an example of such digital isolators which are often used in high-density communications, motor control, and industrial automation applications.

The SI8620BC-B-IS digital isolator from Silicon Laboratories is a bidirectional, solid-state high-density system with isolation voltage up to 2500Vrms. It features digital isolation technology in a 3mm x 3mm QFN package for space-sensitive designs that require both speedy signal transmission and high-voltage isolation.

The primary application field of SI8620BC-B-IS digital isolator includes the manufacturers of Industrial Automation, Motor Control, Network Communications, Security Systems, HVAC Equipment, Battery Management Systems, and Medical Instrumentation. This isolator requires a supply voltage range between 1.6V to 30V for its operation and is capable of operating at temperatures ranging from -40°C to +125°C.

The working principle of the SI8620BC-B-IS Digital Isolator is based on the principle of capacitive coupling. The signal induced in the primary side of the transformer is passed through capacitive couplings without any intermediate cable or other medium in the secondary side. The dielectric layer between the primary and the secondary side of the transformer acts as an isolation barrier. This prevents the flow of signal transients or EMI, hence providing galvanic isolation.

The SI8620BC-B-IS Digital Isolator from Silicon Labs offers reliable and efficient bidirectional signal transmission. It utilizes a dielectric layer to isolate the two sides of the transformer, minimizing noise and increasing signal fidelity. Additionally, the isolator\'s high-density 3mm x 3mm QFN package is ideal for applications which require both speedy signal transmission and high-voltage isolation. In summary, SI8620BC-B-IS Digital Isolator from Silicon Labs offers an excellent solution for industrial automation, motor control, and network communications applications.
