Digital Isolators

The ADUM230E1BRWZ is a type of digital isolator. Digital isolators are devices with electrical isolation or insulation between two or more circuits, allowing electrical signals and power to be transferred between circuits while preventing any current from passing through and physically carrying the isolated signal. They are essential components in safety-critical systems as they prevent incoming signals from emanating out, providing substantial noise immunity and thus avoiding any malfunction or unexpected errors due to electrical noise.

Application Field and Working Principle of the ADUM230E1BRWZ

The ADUM230E1BRWZ is an isolated SIP digital isolator used for signal and power transmission. It consists of an input side and an output side, both separated by a silicon-based isolator barrier. The input side drivers on the ADUM230E1BRWZ create data acquisitions for the output side, which subsequently amplifies the signal via a high bandwidth amplifier and transmits it to the output side.Besides data signal transmission, the ADUM230E1BRWZ can also transfer up to 4A of power with a built-in controller, monitoring the power supply and ensuring the correct current voltage levels. It also features linear output voltage adjustment, power sequencing, and short circuit protection, making it suitable for medical applications, industrial automation, and other applications where power is needed and high isolation performance is required. The ADUM230E1BRWZ facilitates data transmission between devices operating at different voltages in conditions of isolation and noise immunity, making it ideal for safety-critical applications. Its isolator barrier eliminates the necessity of adding a common ground, thus making it easier to design when a system contains multiple circuits. This isolator is also resistant to electrostatic discharge (ESD) and surges, allowing a reliable and secure data transfer.The ADUM230E1BRWZ operates on an input voltage range from 3V to 5.5V and has an industrial temperature range between -40°C and +85°C. It is designed to robustly transmit data and power with a maximum data rate of 20Mbps and a minimum isolation voltage of 1.5 kVrms per UL. The ADUM230E1BRWZ is also designed for high vibration environments, allowing it to withstand the most challenging conditions.

Conclusion

The ADUM230E1BRWZ is a digital isolator designed to transmit data and power between circuits while providing adequate isolation and reliable data transfer in safety-critical environments. It has wide-input voltage range and high bandwidth capabilities, making it suitable for a wide range of applications. Additionally, it is resistant to ESD and surge, has adjustable output voltage levels, short-circuit protection, and can withstand high levels of vibration.
