SI8640BA-B-IUR Working Principle

The SI8640BA-B-IUR employs Magnetic Isolation Technology to achieve a high level of isolation between two digital signal paths. This isolation technology uses a pair of cores with opposite polarity to transfer the digital signal from one side to the other. When the core lines are in the same polarity, the magnetic field created by the core lines creates a barrier which keeps out noise and other interfering signals. The digital signals are then transferred across the barrier without any degradation.

The SI8640BA-B-IUR also uses MOSFETs as the main driver for excellent signal reliability. The MOSFETs are triggered by a high-speed charge pump circuit and they drive the magnetic core lines. This ensures excellent signal transmission, and the resulting isolation performance is electrically tight.

Finally, the SI8640BA-B-IUR employs a variety of protection circuitry. This includes short-circuit and overvoltage protection, as well as thermal protection. All of these features ensure that the device is safe and reliable in operation, even in the most challenging environments.
