Digital Isolators are employed in a wide variety of industrial and commercial applications to protect signal processing systems from hazardous electrical disturbances. They provide a physical barrier to isolate electrically the inputs and outputs of digital systems from one another. This helps to eliminate false signals from being transmitted between systems, minimising the chance of system errors or malfunctions.The working principle of digital isolators is based on the use of optoelectronic devices such as LEDs and photodiodes. An LED is used to send a signal across an isolator while a photodiode is used to receive the signal on the other side. The two components are mounted on opposite sides of an isolator material, such as polymethylmethacrylate (PMMA), which prevents any direct electrical connection between them.When an input signal is received, the LED is illuminated, and the photodiode, which is connected to the output side of the isolator, receives the light signal and converts it into an electrical signal that is sent to the output side. The output signal is thus isolated from the input signal.Digital isolators are widely used in industrial and commercial applications and can be used to protect against noise, electromagnetic interference, static electricity and power surges. They are also used in applications such as motor drives, converters, digital signal processors and power and data lines.Digital isolators are typically designed with two channels, one for inputting data and the other for outputting data. Some designs also feature multiple channels, allowing multiple signals to be transmitted and received simultaneously.Digital isolators are also used in automotive applications such as infotainment systems, navigation systems, driver assistance systems and vehicle control systems. They provide a physical barrier between sensitive electronic components, allowing for safe communication of data and power signals between the vehicle and its control systems.Digital isolators are also used in industrial automation to ensure reliable and secure communication and to protect equipment from electrical noise. They are also employed in medical applications to protect medical devices from electrical shocks.Digital isolators are essential in many applications, helping protect signal processing systems from electrical disturbances and ensuring reliable and secure communication between systems.
