Digital Isolators are technology used to communicate across a physical boundary, usually electrically, while providing galvanic isolation. They provide a digital signal in the form of binary logic (0s and 1s) to the other side of the isolation boundary. This allows two isolated systems or components, which may be running on different voltages and have optically or inductively different waveforms, to communicate with each other. 

The ISO7762FDBQR (Isolated Systems On-Board Receiving System) is a type of digital isolator designed to provide galvanic isolation for transmitting signals across a board or from one board to another. The ISO7762FDBQR is made up of two components, each at opposite ends of the digital isolator, and includes a Transmitter (T), Driver (D), and Receiver (R). It is used in a variety of applications, including industrial and medical, and it simplifies the transmission of data across multiple boards, such as those found in automated industrial or medical equipment.

The ISO7762FDBQR application field and working principle is quite simple. It utilizes a technique known as three-level logic which takes an input that is typically high-voltage from different sources and from the same source. This input is then translated into discrete high and low voltage signals that are sent to a receiver. The receiver then decodes the voltage signals and turns them into digital bits. This data is then sent to the digital isolator, which acts as a tunnel or bridge from one board or system to the other. The digital isolator provides isolation between the two systems and therefore prevents issues such as signal interference or power surges from affecting the output. The receiver then receives the digital bits, which can then be used by the system. This process is repeatable as long as the systems and voltages remain the same.

The ISO7762FDBQR is an ideal solution for transmitting data and other signals across multiple boards, as it is fast, reliable, and energy efficient. It is very easy to implement in multiple applications, with some models offering a host of features such as I2C, SPI, and RS485 communication. The ISO7762FDBQR is also a cost effective solution and is designed for long lasting performance.

The ISO7762FDBQR can also be used in applications that require soft start-up, such as those in industrial automation or medical equipment. This type of isolator can prevent data loss during start-up by sending a binary 1 signal when the power is turned on, signaling that the system is ready to accept data. It is also designed to reduce unwanted heat, as it is made from materials which dissipate heat quickly. This helps to ensure that the system does not overheat.

The ISO7762FDBQR digital isolator is a reliable solution for transmitting data between two systems or across multiple boards. It is designed to provide galvanic isolation and reduce the impact of signal interference and power surges. Additionally, it is easy to implement, cost effective, and energy efficient for a variety of applications. As the technology continues to improve, there are even more applications where digital isolation will be beneficial.
