A digital isolator is an electronic device that provides electrical insulation between two parts of a circuit while still allowing them to communicate digitally.
It works by using optical or magnetic coupling technology to prevent an electrical current from flowing between the two parts of the circuit while still allowing data to be transmitted between them.
This is done by converting digital signals into optical or magnetic signals which are then transmitted across the isolation barrier.
Digital isolators are used in a wide variety of applications including industrial control systems, medical equipment, and automotive systems.
They are especially important in applications where isolation is necessary to prevent damage to sensitive components or to protect users from electric shock.
Digital isolators can also help to reduce interference from electrical noise and reduce the chance of data errors. Digital isolators are becoming increasingly popular as they offer reliable and cost-effective isolation solutions.
The Global EV Digital isolator market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Analog Devices recently launched its new family of iCoupler digital isolators, which can help to protect valuable electronic systems from electrical noise, overvoltage, high-voltage transients and other potentially damaging conditions.
The new family of digital isolators, which is available in three different configurations, is designed to offer up to four times the isolation performance and more than double the power efficiency of traditional digital isolators.
The new iCoupler digital isolators are based on Analog Devices’ patented iCoupler technology, which uses an array of miniature transformers to provide high-speed, high-voltage isolation without any external components or connectors.
The new devices are available in both single-channel and dual-channel versions, and include integrated protection against surge, overvoltage, and reverse-bias conditions.
In addition to Analog Devices, several other companies are also offering digital isolators. Texas Instruments recently announced its new Digital Isolator family that offers up to 3.5 kV of isolation and speeds of up to 1 MB/s.
The devices are designed to provide noise immunity, ESD protection, and robust EMI performance. Other companies offering digital isolators include Silicon Laboratories, which offers its ISO7340 digital isolator family, and Infineon Technologies, which offers its XENSIV line of digital isolators.
Overall, digital isolators are becoming increasingly popular for use in a wide range of applications, such as power supplies, data converters, motor control systems, and industrial automation systems.
By offering high-speed, high-voltage isolation, digital isolators can help to protect valuable electronic systems from electrical noise, overvoltage, and other potentially damaging conditions.
With several companies now offering digital isolators, engineers have more options than ever when it comes to protecting their systems.
