... Device's supply requirements. Switch control logic input (ON) capable of interfacing directly with a low voltage control signal. The FPF2024/5/6/7 respond to an output overload condition by going into constant current mode where the output current is regulated by the load switch. If the overcurrent condition persists beyond the 10ms Blanking Time, FPF2024 and FPF2025 pull the fault signal pin (FLAGB) low and shut-off the switch ...

... Blanking Time of 10ms (typ) from triggering the fault signal (FLAGB) output. If the over-current condition persists beyond the Blanking Time, the FPF2024 and FPF2025 pull the FLAGB pin low and shut the switch off. If the ON pin is kept active, an Auto-Restart feature releases the FLAGB pin and turns the switch on again after 70ms ...

... The minimum current at which the parts will limit the load current is internally set to 100mA. The switch current limiting circuitry is active at all times(Sleep and Wakeup mode) and protects the FPF2024-FPF2027 against excessive load currents in all modes. The proprietary current limiting circuit responds to an over-current condition in 15 µ ...
