... The FPF2140/44 have an auto-restart feature which will turn the switch on again after 450ms if the ON pin is still active. The FPF2142/46 do not have this auto-restart feature so the switch will remain off until the ON pin is cycled. For the FPF2143/47, a current limit condition will immediately pull the fault signal pin low and the part will remain in the constant-current mode until the switch current falls below the current limit ...

... FPF2140/ 42 and FPF2144/46. The FPF2140/44 have an feature which will automatically turn the switch on again after 450ms. For the FPF2142/46, the ON pin must be toggled to turn-on the switch again. With no auto-restart, the FPF2143/47 do not turn off in response to a over current condition but ...
