Working Principles

The FPF2213 operates as a power switch by controlling the flow of current between the input and output pins. When the enable pin (EN) is activated, the FPF2213 allows current to pass through from VIN to VOUT. It continuously monitors the current flow and activates overcurrent protection if the current exceeds the set threshold. In case of excessive temperature, the thermal shutdown protection is triggered, ensuring safe operation.
