Description
FPF2411 is a 6 V / 6 A-rated bi-directional load switch, consisting of a slew-rate-controlled, low-onresistance, P-channel MOSFET switch with protection features. The slew-rate-controlled turn-on characteristic prevents inrush current and the resulting excessive voltage droop on the input power rails. The input voltage range operates from 2.3 V to 5.5 V. Bi-directional switching allows reverse current from VOUT to VIN. The switching is controlled by active-LOW logic input the ONB pin. The FPF2411 is capable of interfacing directly with low-voltage control signal General-Purpose Input / Output (GPIO). The FPF2411 is available in 12-bump, 1.235 mm x 1.625 mm Wafer-Level Chip-Scale Package (WLCSP) with 0.4 mm pitch. Ordering Information Part Number Top RON (Typ.).
