Digital Isolators

Digital isolators are designed to electrically isolate two systems components, integrated circuits or microcontrollers, also known as isolation barriers. Developed to provide immunity from inductive transients, protect delicate electronic circuits from EMI and reduce ground loops. Isolators are used in numerous applications as an efficient way to transfer data and power signals between equipment, while switching and monitoring signals between electronics systems.

SI8610BD-B-ISR Application field and Working Principle

The SI8610BD-B-ISR is a bidirectional digital isolator, which uses transformer technology to provide galvanic isolation and non-contact data and power transmission speeds up to 25 Mbps. It is designed for use in high isolation applications such as signal and power switching between two circuits operating at different voltages. This isolated isolator can be used as both an input and output device (I/O). It features an open collector output, allowing for simple logic switching.

The SI8610BD-B-ISR is available in a wide variety of package types, including dual-in-line (DIP), surface-mount (SMD), and mini-size packages. It is rated for operation at a wide temperature range, from -40°C to 125°C. It is highly reliable and offers up to 1000 V of working voltage, high speed operation up to 25 Mbps, and a low-cost design. It is RoHS compliant, and it meets all the necessary performance and safety requirements for industrial applications.

The SI8610BD-B-ISR provides several functions that enable it to be used in various applications. It is designed to transfer data between two circuits or components while preventing ground loops. It also offers switching and monitoring of signals over long distances without the need for wiring, thus saving space. in addition, the device is capable of providing signal direction manipulation, allowing for various output modes such as open drain and high speed complementary output.

The operation of the SI8610BD-B-ISR is based on a transformer technology, which places two windings of the transformer in the primary and secondary side of the circuit. The data is transferred and switched between the two sides using the transformers windings, which have different high and low flows due to the design of the transformer. The transformer isolates the two sides and provides the required isolation barrier. The open collector output is enabled by a FET device, which is operated by a control signal from one side to the other. If the control signal is low, the FET gate will open, allowing for switching and completion of the desired operation.

In summary, the SI8610BD-B-ISR is a low-cost and highly reliable digital isolator that provides data and power transmission speeds up to 25 Mbps. It is RoHS compliant and compliant with UL, CSA, and CE standards. It is suitable for numerous applications that require high speed and voltage isolation, including signal and power switching between two circuits operating at different voltages. The transformer technology of the device provides smart data transmission, signal direction manipulation, and open collector output, all adding up to the performance and reliability of this isolator.
