Working Principles

The LTC4355CS#TRPBF works by continuously monitoring the input voltage and comparing it to the set overvoltage and undervoltage thresholds. When the input voltage exceeds the overvoltage threshold, the IC disconnects the load from the source, preventing any potential damage. Similarly, when the input voltage falls below the undervoltage threshold, the load is disconnected to protect the system. The adjustable overvoltage lockout feature allows customization of the threshold to match specific application requirements.
