Digital isolators are an important component in any modern electronic system. They help to provide electrical isolation of the components in a system, and can also provide the essential protection from voltage transients and ESD events. The SI8710AC-B-IPR is a digitally-enhanced, high-performance isoaltor from Silicon Labs. In this article, we’ll look at the SI8710AC-B-IPR’s application fields and working principle.

Application Fields

The SI8710AC-B-IPR digital isolator offers a wide-range of features and benefits, making it suitable for a variety of applications. It provides a typical propagation delay of 4.5 ns, and a peak common-mode transient immunity of 24 kV/μs. This makes it well-suited for applications involving high-speed communication protocols and large surges in the common mode. It is also rated with an operating temperature range of -40°C to +105°C, making it suitable for use in a wide range of industrial, automotive, medical and consumer applications.

In terms of voltage withstand, the SI8710AC-B-IPR digital isolator provides optical coupling with a minimum voltage withstand of 8.7 kV while operating in the steady-state mode. It also features low leakage current and low power consumption, making it highly efficient for a variety of applications. It is available in a wide range of packages, offering customers plenty of flexibility when it comes to device integration.

Working Principle

At the heart of the SI8710AC-B-IPR is a proprietary optically-isolated digital transistor technology, which allows the device to provide electrical isolation. This technology utilizes two photodiodes, a launch diode and a receive diode, which are configured in a special compound structure to form an electrically-isolated virtual cell. If an electrical signal is introduced into one end of the structure, the optical coupling between the two photodiodes ensures that the signal is transmitted across the cell without direct electrical contact.

Once the signal is transmitted across the isolator, it is converted to a digital signal by the in-built transistor. This digital signal is then amplified and transmitted back to its original source. This allows the SI8710AC-B-IPR to provide isolation at speeds of up to 100 Mbps, with a typical propagation delay of 4.5 ns and a peak common-mode transient immunity of 24 kV/μs.

To provide the ultimate level of protection, the SI8710AC-B-IPR also supports a ruggedization feature which significantly reduces the risk of ESD failure. It has been designed to internally clamp ESD voltages up to a maximum of 8 kV, providing extra protection against transient events.

Conclusion

The SI8710AC-B-IPR is an advanced digital isolator which is suitable for a range of different applications. With its unique optically-isolated digital transistor technology, it is capable of providing electrical isolation at speeds of up to 100 Mbps, with a typical propagation delay of 4.5 ns and a peak common-mode transient immunity of 24 kV/μs. It also offers a minimum voltage withstand of 8.7 kV, low leakage current and low power consumption, making it highly efficient for a variety of applications.
