... ON pin is still active. The FPF2194 does not have this auto-restart feature, so the switch remains off until the ON pin is cycled. The FPF2195 does not turn off after a current limit fault, but remains in the constant-current mode indefinitely. The minimum current limit is 100mA. ...

... 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 ...

... Application Information Setting Current Limit The FPF2193, FPF2194, and FPF2195 current limit is set with an external resistor connected between I and GND. This resistor is selected using the following equation: 551 SET I LIM is in Ω and Amps. SET SET Table 1 can also be used to select R application would be the 500mA current required by a single USB port ...

... Once this temperature has been reached, toggling ON does not turn the switch on until the junction temperature drops. For the FPF2195, a short on the output causes the part to operate in a constant- current state, dissipating a worst-case power of: = × ...
