... IN 140° active HI and has a low threshold making it capable of interfacing with low voltage signals. In addition, excessive currents will cause the switch to turn off for 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 ...

... For the IN FPF2140/44, 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 the thermal shutdown activates. It will then cycle in and out of thermal shutdown so long as the ON pin is and active and the short is present ...
