Digital isolators are designed to electrically isolate two circuits by transmitting a signal in digital form, instead of using an opto-coupler. This means the isolation performance is unaffected by voltage spikes, current transients, or environmental parameters. The SI8622EC-B-IS digital isolator is a small solution designed to meet the demanding requirements of consumer, industrial, automotive and medical applications. This isolator features a low active power of 6.3 mW, an operating temperature range from -40°C to 125°C, and a response time to less than 2 µs.

The SI8622EC-B-IS digital isolator is an integrated circuit that utilizes digital signal (DS) logic to provide 1700 VDC of electrical isolation. It works by interacting with two bidirectional channels on one dam and an internal isolator on the other. The two channels are connected to a CMOS logic input/output on the control side and logic-level synchronization signals on the other side. Each of the channels then transmits and receives logic-level data, in which the logic-level output data from the input side connects back to the input side via two internal isolators. In this configuration, power is provided from both sides, allowing for bidirectional communication.

The SI8622EC-B-IS digital isolator is an excellent choice for applications such as motor control, solenoid valve control, relays, switches, and automotive. It is ideal for situations where there are significant power differences between supply and load. The low active power and short response time make it great for complex system designs where an isolation interface is necessary. Additionally, the wide temperature range makes it suitable for use in extreme operating conditions.

The SI8622EC-B-IS digital isolator is a flexible, reliable solution. Thanks to the combination of features, including high isolation voltage, low active power, short response time, and wide temperature range, it is fully capable of meeting the needs of a variety of applications. The digital isolator is user-friendly and provides a robust solution for applications requiring isolation and communication between different voltage levels.
