Why do you need a Digital Isolator?
A digital isolator is essential for protecting sensitive low-voltage components in systems that involve high-voltage interfaces, preventing unwanted currents or noise from crossing over and potentially damaging circuitry. A multi-channel configuration offers engineers flexible isolation for several data lines within a single package, allowing for simultaneous, secure isolation of diverse signals such as SPI, control, and feedback channels. This not only simplifies design but also enhances safety, stability, and data integrity in complex, high-performance applications.
