... The FPF2201 do not have this auto-restart feature so the switch will remain off until the ON pin is cycled. For the FPF2202, 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 ...

... FLAGB remains LO through the Auto-Restart Time for the FPF2200 while for the FPF2201, FLAGB is latched LO and ON must be toggled to release it. With the FPF2202, 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 ...

... Once this temperature has been reached, toggling ON will not turn-on the switch until the junction temperature drops. For the FPF2202, a short on the output will cause the part to operate in a constant current state dissipating a worst case power of: ...
