Digital isolators are useful for providing reliable connections between two systems without introducing ground loops or additional noise. The SI8620AB-B-ISR is a digital isolator that can provide long-term, reliable operation in even extreme environments. The device’s isolated power supply ensures safety and long-term reliability, while its broad temperature range makes it suitable for harsh industrial environments.

The SI8620AB-B-ISR is a high voltage digital isolator designed for applications with common-mode voltages up to 3.75V and transistors up to 20V. It is a bi-directional isolation device which can be used to isolate power between separate line modules. The device is also suitable for isolating signals between systems on different voltage levels. The isolation performance is typically 1MV isolation voltage at the transistors, resulting in long term, durable isolation between systems.

The SI8620AB-B-ISR is built on a CMOS substrate, it can operate from a wide range of input voltages, and it features 5V supply. The device enables signals to be transmitted and received with high frequency up to 3Mbps. Thanks to its 4 GHz common-mode rejection, extremely low propagation delay and low noise, the SI8620AB-B-ISR makes it suitable for various fields ranging from medical to industrial.

The SI8620AB-B-ISR can function in both isolated digital signaling and power supply isolated signal exchange applications. By storing power supply voltage it can support up to 9 power bus signals for each line. It also supports single ended signals up to 3V and differential voltage signals up to 10mV.Integrated protections allow the device to exceed 1500V applied through its terminals without any damage.

The SI8620AB-B-ISR employs a variety of technologies to ensure the isolation is well maintained: galvanically isolated power, bi-directional transmitting and receiving, robust ESD protection on its inputs and outputs, and a low emission level. These provide the highest levels of safety and performance. The device employs an isolated package that contains an integrated transmission channel, allowing information to be transmitted from one stage to the other without any leakage or contact.

In industrial applications, the SI8620AB-B-ISR can be used for communications between two systems with large voltage differences, or to isolate the power of two different systems without compromising performance. Moreover, it can also be used in medical and automotive applications, where it can provide reliable, long-term performance.

The SI8620AB-B-ISR is increasingly being used in applications where high performance and reliable operation are critical such as solar systems, power plants, industrial machinery, HVAC systems and automotive electronics. It is an ideal choice for any system that requires reliable power or signal isolation.
