... Description of Operation The FPF2172 is a current limited switch that protects systems and loads which can be damaged or disrupted by the application of high currents. The core of the device is a 0.125Ω P-channel MOSFET and a controller capable of functioning over a wide input operating range of 1.8-5.5V paired with a low forward voltage drop Schottky diode for reverse blocking ...

... To be most effective, the input and output capacitors should be placed close to the device to minimize the effects that parasitic trace inductances may have on normal and short-circuit operation. Using wide traces for V IN minimize parasitic electrical effects along with minimizing the case to ambient thermal impedance. FPF2172 Rev FPF2172 ON FLAGB GND 5 ...
