Working Principles

The LTC4365HDDB-1#TRMPBF utilizes a combination of internal circuitry and external components to monitor and control the input voltage. It continuously compares the input voltage with the adjustable thresholds set by the user. If the voltage exceeds the overvoltage protection threshold, the device quickly shuts off the gate drive output, protecting downstream components. Similarly, if the voltage falls below the undervoltage lockout threshold, the device disables the circuit to prevent unreliable operation. Additionally, the LTC4365HDDB-1#TRMPBF ensures that current flows in the correct direction by blocking reverse voltage.
