... 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. The minimum current limit is 150mA ...

... Auto-Restart Time for the FPF2165. For the FPF2164, FLAGB is latched LO and ON must be toggled to release it. With the FPF2165, 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 ...

... Application Information Typical Application Battery 1.8V-5.5V OFF 4.7µF Setting Current Limit The FPF2163, FPF2164, and FPF2165 have a current limit which is set with an external resistor connected between ISET and GND. This resistor is selected by using the following equation, 275 SET I LIM Ohms and that of I ...

... Once this temperature has been reached, toggling ON will not turn-on the switch until the junction temperature drops. For the FPF2165, a short on the output will cause the part to operate in a constant current state dissipating a worst case power of, ...
