... FLAGB remains LO through the Auto-Restart Time for the FPF2213 while for the FPF2214, FLAGB is latched LO and ON must be toggled to release it. With the FPF2215, FLAGB is LO during the faults and immediately returns HI at the end of the fault condition. FLAGB is an open-drain MOSFET which requires a pull-up resistor between VIN and FLAGB ...

... Application Information Setting Current Limit The FPF2213, FPF2214, and FPF2215 have adjustable high precision current limit which is set with an external resistor connected between ISET and GND. Please see the layout recommendation section of the application note for the recommended R layout. The R SET ...

... Once this temperature has been reached, toggling ON will not turn-on the switch until the junction temperature drops. For the FPF2215, a short on the output will cause the part to operate in a constant current state dissipating a worst case power of: ...

... Load current can be scoped by removing the R4 resistor and soldering a current loop to the R4 footprint. Thermal performance of the board is improved using a few techniques recommended in the layout recommendations section of datasheet.
