Digital Isolators

Digital isolators are devices used to separate electrical signals from each other. The basic purpose of an isolator is to provide galvanic isolation between two or more wires, while allowing communication between them. This prevents high voltages in one wire from transferring to the other wire, resulting in damage to components, people and property. The SI8610BC-B-IS is a galvanic digital isolator and it has a number of unique features that make it suitable for a wide variety of applications.

Features and Specifications

The SI8610BC-B-IS is a full bridge digital isolator that has two independent channels. It features a wide operating temperature range, from -40°C to +105°C, and a high isolation voltage of 3000 VDC. It is designed to handle voltages up to 24 VDC, has a dielectric strength of 1000 Vrms, and has a capacitance of 1.5pF. It has a conversion time of just 7ns, making it ideal for high speed applications. The SI8610BC-B-IS is also available in a wide variety of packages, including both SMD and through-hole types.

Application Field and Working Principle

The SI8610BC-B-IS is a perfect fit for applications that require digital isolation. It can be used in medical devices, automotive applications, and industrial automation systems. It is perfect for applications that require high data transfer rates and greater accuracy. The device works by transferring signals from one side to the other without creating a physical connection between them. This is accomplished by using a combination of capacitive coupling and transformer isolation.

In capacitive coupling, a very small capacitance is created across the two separated sides. Signals on one side induce these capacitors and the charge is transferred to the other side. Transformer isolation works by passing signals through a transformer. This transformer isolates the two sides electrically, but is still able to transfer signals between them. The combination of these two techniques allows the SI8610BC-B-IS to effectively isolate both sides while still allowing data to be transferred.

Conclusion

The SI8610BC-B-IS is a versatile digital isolator designed for a wide range of applications. It has a wide operating temperature range, a high isolation voltage, and a fast conversion time. It uses a combination of capacitive coupling and transformer isolation to provide effective galvanic isolation and signal transfer. This makes it perfect for applications that require high data transfer rates, greater accuracy, and reliable isolation.
