Working Principle

The working of the digital isolator SI8462AB-A-IS1 is based on the principle of galvanic isolation, wherein an electrically conductive wall is created between two circuits. The isolator utilizes an isolation barrier, typically a light-based system, to create a high-impedance shield between the two circuits. This isolator works with optically coupled isolator elements that modulate an LED transmitter on one side and a detector on the other side.

The optical isolation barrier creates a tight, electrical link between the input side and the output side, while keeping the two circuits electrically isolated from each other. The isolator converts the input signal into a digital signal, which is then transmitted via the isolation barrier. At the output side, the digital signal is again converted into an analog signal and provided at the output pins. This way, the SI8462AB-A-IS1 can isolate both power and signals from one circuit to the other.

The SI8462AB-A-IS1 digital isolator is also designed to provide high levels of noise immunity and transient protection. It features an isolation voltage of 8 kV, a signal bandwidth of 1 Mbps, and a maximum switching speed of 50 ns. Further, it is designed to efficiently dissipate power with a low quiescent current and a low-power shutdown mode. This makes it an ideal choice for high-performance digital isolation applications.

In addition, the SI8462AB-A-IS1 is capable of offering superior data integrity of digital signals over a wide range of temperatures, making it suitable for a variety of industrial and automotive applications. Additionally, it is designed to meet the highest standards of quality, reliability, and design, ensuring that it is able to meet the most demanding isolation requirements.
