FPF1048BUCX

Description

The FPF1048 advanced load management switch targets applications requiring a highly integrated solution. It disconnects loads powered from the DC power rail (<6 V) with stringent off-state current targets and high load capacitances (up to 100 µF). The FPF1048 consists of slew-rate controlled lowimpedance MOSFET switch (23 mΩ typical) and integrated analog features. The slew-rate controlled turn-on characteristic prevents inrush current and the resulting excessive voltage droop on power rails.
