... FPF2194, the FLAGB goes LOW at the end of the blanking time, while FLAGB goes LOW immediately for the FPF2195. FLAGB remains LOW through the auto- restart time for the FPF2195. For the FPF2194, FLAGB is latched LOW and ON must be toggled to release it. With the FPF2195, FLAGB is LOW during the faults and immediately returns HIGH at the end of the fault condition ...

... V and GND. This capacitor prevents parasitic board OUT inductances from forcing V switch turns off. For the FPF2193 and FPF2194, the total output capacitance needs to be kept below a maximum value, C registering an over-current condition and turning off the switch. The maximum output capacitance can be ...

... This is more power than the package can dissipate, but the thermal shutdown of the part activates to protect the part from damage due to excessive heating. When using the FPF2194, attention must be given to the manual resetting of the part. The junction temperature is only able to increase to the thermal shutdown threshold ...
