... ON pin is still active. The FPF2002 and FPF2006 do not have this auto-restart feature so the switch will remain off until the ON pin is cycled. For the FPF2003 and FPF2007, 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 ...

... For the FPF2002 and FPF2006, the ON pin must be toggled to turn-on the switch again. The FPF2003 and FPF2007 do not turn off in response to a over current condition but instead remain operating in a constant current mode so long active and the thermal shutdown or under-voltage lockout have not activated ...

... ON will not turn-on the switch until the junction temperature drops. For the FPF2003 and FPF2007, a short on the output will cause the part to operate in a constant current state dissipating a worst case power as calculated in (3) until IN the thermal shutdown activates. It will then cycle in and out of ...
