Digital isolators are widely used components in a wide range of areas from consumer electronics to medical technology, communications and electric mobility. They are utilized to galvanically separate two different systems or components from each other to protect their respective circuits from overvoltage, power burn-out or other short-circuiting equipment. The ADUM2402CRWZ-RL is one such digital isolator and its application field and working principle are described below.

The ADUM2402CRWZ-RL is a high-speed digital isolator with integrated signal conditioning. With its bidirectional Isolation range up to 10kV, it is designed to transmit digital signals between isolated sections in circuits or systems. It has an operating temperature range between -40°C to +85°C and is designed to withstand high temperatures and humidity. It has built-in surge protection, over-voltage protection, short-circuit protection, and under-voltage lockout. It also features dual-channel bi-directional Isolation and 6 dB typ. noise immunity.

The way it works is relatively simple. It basically acts as a very small and fast switch, which carries the electric signal from one system to another. It is composed of two separate sections - a high side and a low side - each featuring its own segregated signal path. When the signal from one side is sent to the other, it is transmitted as a low-amplitude DC signal at a very high frequency. The high frequency ensures that the signal is not distorted while passing along the wires. This helps to prevent any unintended signals from entering the other system. This is especially useful in applications where the safety and reliability of the signals is of utmost importance.

The ADUM2402CRWZ-RL is suitable for applications in automotive systems, battery management, industrial systems, medical systems, and other digital systems. It can be used to protect sensitive electronic circuits from electrical over-currents, over-voltage, and short circuits, as well as to provide high-speed communications between isolated sections. This digital isolator offers high-reliability and is compliant with the relevant automotive standards, such as ISO16750, Safety of Road Vehicles: Electrical Equipment and ISO16949: Quality Systems.

In conclusion, the ADUM2402CRWZ-RL digital isolator is an ideal choice for applications requiring a reliable and high-speed isolated interface. It is designed to withstand high temperatures and humidity, offers surge protection, over-voltage protection, short-circuit protection, and under-voltage lockout, and provides a bidirectional Isolation range up to 10kV. It is suitable for automotive systems, battery management, industrial systems, medical systems, and other digital systems.
