Working Principles

The LTC4352HMS#PBF works by continuously monitoring the input voltage and comparing it to the set thresholds for overvoltage and undervoltage conditions. When an overvoltage condition is detected, the external MOSFET is turned off to protect the system. Similarly, if the input voltage falls below the undervoltage lockout threshold, the MOSFET is disabled to prevent unreliable operation. The fault flag output provides a signal to indicate the occurrence of a fault condition.
