... For the FPF2201, if the constant current condition still persists after 30ms, these parts will shut off the switch and pull the fault signal pin (FLAGB) low. The FPF2200 has an auto-restart feature which will turn the switch on again after 450ms if the ON pin is still active. The FPF2201 do not have this auto-restart feature so the switch will remain off until the ON pin is cycled ...

... FLAGB signals the fault mode by activating LO. In the event of an over-current condition for the FPF2200 and FPF2201, the FLAGB goes LO at the end of the blanking time while FLAGB goes LO immediately for the FPF2202. If the over-current condition lasts longer than ...
