... If the over-current condition persists beyond the blanking time, the FPF2700 latches off and shuts the switch off (Figure 32). If the ON pin is kept active, an auto-restart feature releases the switch and turns the switch on again after the auto-restart time (Figure 33). If the over-current condition persists beyond the blanking time, the FPF2701 latch-off feature shuts the switch off ...
