Digital isolators are components which allow multi-circuit signals to be transferred with low-noise and high-accuracy while keeping them isolated from mains power circuits or other electric parts. These devices especially help improve safety in high-voltage appliances where power supply and function signals coexist.

The ISO7220MDRG4 is a special digital isolator designed specifically for applications like Medical Diagnostic Equipment, Motor Control Systems, and even Industrial Automation Applications. This device is capable of working in a temperature range of -40 to 125°C, and offers a robust and proven Fastened Mode isolation structure with galvanic isolation of up to 1000Vrms. It features a bidirectional transmission speed of up to 12 Mbps and provides a wide operating voltage range of 3.3 V to 5.5 V. It also comes with a low propagation delay of 12 ns per channel and an integrated voltage regulator, enabling accurate data transmissions between circuits with different voltage levels.

The working principle of the ISO7220MDRG4 is quite simple. Its bidirectional inputs-outputs enable analog and digital signals to be detected and transferred with low-noise and high-accuracy over a wide temperature range and in an isolated environment. Its integrated voltage regulator allows the signals to be transmitted between different voltage levels without any external components. Furthermore, its integrated switch circuit keeps the circuit from being overloaded and has a built-in overvoltage protection and EFT noise filter.

The ISO7220MDRG4 has a wide application field due to its low-power consumption, wide operating voltage range, and low propagation delay per channel. It is often used in medical diagnostic equipment, motor control, and other industrial automation applications. It can be used in high frequency switching applications in low voltage direct current systems, as well as in high speed communication applications. These include current sensing solutions like current loops and safety/mute functions. It can also be used in automotive ECUs, inverters, medical/testing gear, real-time control systems, low-voltage DC motors, and on-board electronic systems.

Therefore, the ISO7220MDRG4 is a reliable digital isolator component with a wide application field and a robust and proven Fastened Mode isolation structure. It is characterized by high-accuracy signal transmission with low-noise and isolation from mains power circuits or other electrical parts. Additionally, its integrated voltage regulator and no external components required give it even more value when it comes to applications like Motor Control, Medical Diagnostic Equipment, and Industrial Automation Applications.
