Supply original FPF1039UCX, PMIC - Power Distribution Switches, Load Drivers, by ON Semiconductor

The FPF1039 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 FPF1039 consists of slew-rate controlled low-impedance MOSFET switch (21 mΩ 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.
