Digital Isolators

Digital Isolators are designed to provide an isolated interface between two systems to protect them from ground loops, noise, and other potential issues. A SI8651BC-B-IS1 isolator, for example, is a bidirectional, voltage-mode isolator based on digital signal processing (DSP) technology.

Application Field

SI8651BC-B-IS1 digital isolators are ideal for data conversion applications requiring high-precision, high-reliability, and advanced performance. These isolators are especially useful in industrial automation, medical, and automation systems. In particular, they are used to protect sensitive communications equipment, sensors, actuators, and other components.

Features

SI8651BC-B-IS1 isolators feature a low propagation delay of 4.5µs, making them ideal for high-speed communication applications. They also support high accuracy with a linearity of 0.1%FS, making them suitable for applications that require precise measurements. The SI8651BC-B-IS1 also features a wide operating temperature range of -40°C to +85°C and low power consumption of 50mW. It has a maximum isolation voltage rating of 1000Vrms and comes with surge immunity of up to ±4kV line-to-line.

Working Principle

The SI8651BC-B-IS1 isolator works by using capacitive coupling between input and output (Tx and Rx). The Rx side is connected to a chip which senses the receiving signal. The Tx side is connected to a chip which controls the transmission of signal. The differential signals are transmitted through the capacitive isolation, ensuring that the two sides of the isolation are electrically isolated from each other. The isolator is capable of isolating two systems from each other, both from an electrical and a data transmission standpoint. The transmission of data is usually handled through a serial protocol. The protocol is based on either a Manchester code or a differential Manchester code. The former is used when transmitting a static voltage level over a longer period of time, while the latter is used for more secure transmission, such as communicating with a microcontroller.

Conclusion

The SI8651BC-B-IS1 digital isolator is an ideal solution for applications that require precise measurements and reliable data transmission. Its low propagation delay, high accuracy and wide operating temperature range make it suitable for a variety of industrial and medical applications. It also offers good protection from ground loops, noise, and other potential issues, making it the perfect choice for isolating two systems from each other.
