Working Principles
The LTC4412MPS6#TRMPBF controls the forward voltage drop across an external P-channel MOSFET. When the input voltage is higher than the output voltage, the controller turns on the MOSFET, allowing current flow from the input to the output. This ensures power supply redundancy and load sharing in multiple power supply systems.
The controller also protects against reverse current flow by blocking current from flowing back into the input source. It monitors the input voltage and provides a fault output when overvoltage conditions occur, indicating a potential fault in the power supply system.
