Working Principles

The LTC4365IDDB#TRPBF utilizes a combination of internal circuitry and external components to provide overvoltage and reverse voltage protection. It monitors the input voltage continuously and compares it to the set thresholds. When an overvoltage or reverse voltage condition is detected, it disconnects the load from the input source to prevent damage to the sensitive electronic components.
