... FPF2025 pull the fault signal pin (FLAGB) low and shut-off the switch. An Auto-Restart feature turns FPF2024 and FPF2025 on again after 70ms if the ON pin is still active. The FPF2026 has a Latch-Off feature which shuts off the switch off after the expiration of the 10ms Blanking Time and keeps it off until the ON pin is toggled ...

... By turning on the Q transistor, the 7.5Ω is loaded to the =1.6V IN output voltage and simulates an over-current condition. The R2 resistor is connected between FLAGB pin and input voltage as pull-up resistor for FPF2024, FPF2026 and FPF2027 devices. The FPF2025 does not require a pull-up resistor due to its , and the Over CMOS output structure. RSTRT ...
