... The FPF2213 has an auto-restart feature, which will turn the switch on again after 450mS if the ON pin is still active. The FPF2214 do not have this auto-restart feature so the switch will remain off until the ON pin is cycled. For the FPF2215, a current limit condition will immediately pull ...

... FLAGB signals the fault mode by activating LO. In the event of an over-current condition for the FPF2213 and FPF2214, the FLAGB goes LO at the end of the blanking time while FLAGB goes LO immediately for the FPF2215. If the over-current condition lasts longer than ...

... I LIM (Min) GND. This capacitor will prevent parasitic board inductances from forcing V FPF2213 and FPF2214, the total output capacitance needs to be kept below a maximum value, C part from registering an over-current condition and turning-off the switch. The maximum output capacitance can be determined from the following formula: ...
