... The FPF2163 has an auto-restart feature which will turn the switch on again after 450ms if the ON pin is still active. The FPF2164 does not have this auto-restart feature so the switch will remain off until the ON pin is cycled. The FPF2165 will not turn off after a current limit fault, but will rather remain in the constant current mode indefinitely ...

... FPF2163 and FPF2164. The FPF2163 has an Auto-Restart feature which will automatically turn the switch on again after 450ms. For the FPF2164, the ON pin must be toggled to turn-on the switch again. The FPF2165 does not turn off in response to an over current condition but instead remains operating in a constant current mode so long active and the thermal shutdown or undervoltage lockout have not activated ...

... This is more power than the package can dissipate, but the thermal shutdown of the part will activate to protect the part from damage due to excessive heating. When using the FPF2164, attention must be given to the manual resetting of the part. The junction temperature will only be able to increase to the thermal shutdown threshold ...
