Working Principles

The LTC4224IMS-2#PBF operates by continuously monitoring the input voltage and comparing it with the user-adjustable overvoltage and undervoltage thresholds. When the input voltage exceeds the set overvoltage threshold, the IC shuts off the external MOSFET to protect downstream components. Similarly, if the input voltage falls below the undervoltage threshold, the MOSFET is turned off to prevent underpowered operation. The IC also incorporates current limiting and short-circuit protection to safeguard against excessive current flow. In case of any fault condition, the FLT pin provides an indication signal.
