Digital isolators are devices that electrically isolate two systems while providing interface and signal conversion between them. They are mainly used in electronic circuits to protect sensitive components from improper operation in the presence of a transient or prolonged overvoltage. It is specially designed to perform a variety of functions, including isolation of signals between two circuits, bidirectional data transmission, electromagnetic compatibility (EMC) immunity and others. One of the most commonly used digital isolators is the ISO7762DBQR.

The ISO7762DBQR is a quad bidirectional non-isolation digital isolator that provides two-way isolation of up to 4 isolated channels with common-mode transient protection of up to 25 kV/μs. It is suitable for applications in which signal integrity and accuracy are paramount, and offers far superior performance compared to traditional galvanic isolation technologies. The device integrates four NMOS pass-transistors and four npn bipolar transistors that provide unmatched protection for any transfer of digital signals.

The ISO7762DBQR digital isolator operates two isolated channels between two isolated power supplies. The two isolated power supplies are both protected from each other and from any possible disturbances generated by external sources. The digital isolator driver contains a pair of npn clamping transistors that protect the isolated power supply from any overvoltage going in either direction. In this way, the ISO7762DBQR can be used for any transfer of digital signals between two isolated circuits with far superior performance compared to traditional galvanic isolation technologies.

The ISO7762DBQR digital isolator also has a built-in overvoltage protection that prevents any circuit misbehavior due to overload conditions. The overvoltage protection features are configured to cover all supply rails above -15 V and +15 V to provide a reliable isolation even in highly competitive environments. With the built-in overvoltage protection, the ISO7762DBQR can protect the isolated circuit from any voltage-related problems.

The ISO7762DBQR digital isolator provides two-way isolation of up to 4 isolated channels with common-mode transient protection of up to 25 kV/μs. Furthermore, it is also designed to protect the circuit from any possible EMI interferences that may occur due to external sources. The device is suitable for applications in the automotive, medical, industrial, test and measurement, and consumer electronics industries that require reliable isolation of signals between two systems.

In summary, the ISO7762DBQR digital isolator is a highly reliable device used to protect electronic circuits from improper operation in the presence of a transient or prolonged overvoltage. It provides excellent two-way isolation of up to 4 isolated channels with common-mode transient protection of up to 25 kV/μs. It is suitable for various applications and offers far superior performance compared to traditional galvanic isolation technologies. It also provides built-in overvoltage protection to protect the circuits from any voltage-related problems. Hence, the ISO7762DBQR digital isolator is the ideal solution for high-performance and reliable signal transfer in a wide range of industries.
