Digital Isolators

SI8610ED-B-ISR is a type of digital isolator produced by IXYS Integrated Circuits Division. This isolator provides galvanic isolation for power control applications such as motor drives and lighting controls, current sensing, and power line communication. It is designed to meet the requirements of high-voltage applications, offering reliable, durable isolation with low power dissipation and high efficiency.

Application Field

SI8610ED-B-ISR is ideal for high-voltage applications requiring galvanic isolation. It can be used to protect data transmitted over power lines, provide interference suppression between circuits, and isolate power control circuits.

The device is a perfect solution for safety-critical applications such as motor drives, lighting controls, and industrial equipment, which require galvanic isolation to facilitate circuit operation and protect against high-voltage transients.

The device is also used in applications where wide power supply range, as well as high-voltage isolation and low power dissipation are requirements. Such applications include power over Ethernet (PoE), power line communication, electric vehicle charging, and solar microinverters.

Working Principle

SI8610ED-B-ISR utilizes a monolithic high-voltage isolation component that provides galvanic isolation up to 2 kV rms between the input and output of a circuit. The device is a low power digital isolator with a low on-resistance switch network, which ensures high switching efficiency and low power dissipation.

The device also offers active level shifting for interfacing high-voltage and low-voltage logic devices. The active level shifting allows it to tolerate a large DC offset between the input and output signals, while still maintaining logic levels.

The device is designed to meet the requirements of high-voltage applications while providing high efficiency, high isolation and low power dissipation. It is a reliable and durable isolator that can be used in safety-critical applications such as motor drives and lighting controls.
