Digital Isolators The SI8635BT-ISR is a digital isolator module with magnetic coupling and bi-directional data transmission technology used in electronic systems. This type of isolator is an upgrade of the optocoupler, which offers fast data transmission and isolation against both voltages and currents while being more cost-efficient.The SI8635BT-ISR is designed to provide reliable isolation between two components, even in very noisy and hostile environments. Its design is based on the principles of bi-directional power transmission, which is a high-frequency signal transmission technology used to connect and disconnect high-power components without interruption. By using the magnetic coupling, this isolator can protect the system from shocks and surges caused by electricity in sensitive and delicate components.In terms of its working principle, the SI8635BT-ISR has two parts – the isolator core and the bridge circuit. The isolator core is the main part of the device, which is a series of transformers, inductors, and capacitors coupled in a specific configuration. This core increases the isolation rating of the isolator and prevents large AC and DC voltage differences between two components.On the other hand, the bridge circuit is composed of four diodes configured in a bridge pattern, which provides bi-directional data transmission. The bridge circuit acts as an electronic gate, which allows data to pass through when the high voltage is over the bridge’s threshold and isolates the two components when the voltage is below the threshold. In terms of its application fields, the SI8635BT-ISR is mainly used in industrial control systems (DCS and PLCs), automotive electronics, portable medical devices, and many other industries requiring a reliable level of isolation and protection against electrical shocks and damages. The SI8635BT-ISR can provide isolation of up to 690V RMS, ensuring an uninterrupted power supply and reliable operation. It has also passed several tests such as the UL1577 (Isolation, Surge, and Overload Testing), EN60715 (dynamic voltage shifting tests), EN50155 (electromagnetic compatibility tests), and Mil-Std-883C (environmental tests).Overall, the SI8635BT-ISR is a great option for those looking for a reliable digital isolator that can provide maximum protection against electrical shocks and damages. It offers an unbeatable combination of fast data transmission and isolation up to 690V RMS, making it a great choice for any application.
