Digital isolators (DI) provide optical isolation of digital signals between equipment and systems. Isolation is an important method for preventing digital signals from interfering with each other, and also a key engineering measure to protect equipment and systems from breach and failure. The use of digital isolators thus permits the installation of multiple types of instruments or other equipment and systems in a shared environment.

ISO15DWR is a novel, high-performance digital isolator developed in the recent few years. It is designed to provide a reliable, low latency, wide isolation range, and improved power safety in a wide variety of applications. The ISO15DWR isolator is composed of an active monolithic CMOS isolator (ADI FET-CMOSTM) and a specialized passive filter network. It provides an isolation voltage of up to 100V and an isolation time of up to 40 ns. It also offers an isolation range up to 500V, which makes it ideal for many industrial applications.

The application field of ISO15DWR isolators is broad, including industrial applications such as factory automation, control systems, communication systems, power systems, security systems, biomedical and healthcare applications such as medical instrumentation, and aerospace and defense applications such as aircraft, spacecraft, and satellite systems. It also applies to automotive applications such as airbags, ABS and ECUs.

The working principle of ISO15DWR isolator is based on a filter network composed of active monolithic CMOS and passive components. The active CMOS component detects the rising and falling edges of the digital signals. This detected signal is filtered through several active components, and then the filtered output is connected to the isolated side. In this way, data signals from both sides of the isolation barrier can be transmitted without any losses. The advantage of this working principle is that it significantly reduces the latency of data transmission, making it ideal for real-time applications.

The ISO15DWR isolator is a reliable and versatile solution for all kinds of isolation requirements. Its advanced design and filter network allow it to be deployed in a wide variety of applications, from industrial control systems and energy systems to medical equipment and aerospace equipment. Moreover, its improved power safety guarantees that it will be a reliable and dependable solution for now and the future.
