Description

The FPF1038 advanced load-management switch target applications requiring a highly integrated solution for

disconnecting loads powered from DC power rail (<6 V) with stringent shutdown current targets and high load

capacitances (up to 200 µF). The FPF1038 consists of slew-rate controlled low-impedance MOSFET switch(21 m

typical) and other integrated analog features. The slew-rate controlled turn-on characteristic prevents inrush current and the resulting excessive voltage droop on power rails.
