FPF1039UCX

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. This device has exceptionally low shutdown current drain (< 1 μA maximum) that facilitates compliance in low standby power applications. The input voltage range operates from 1.2 V to 5.5 V DC to support a wide range of applications in consumer, optical, medical, storage, portable, and industrial device power management. Switch control is managed by a logic input (active HIGH) capable of interfacing directly with low - voltage control signal / GPIO with no external pull - up required. The device is packaged in advanced fully “green” 1mm x 1.5 mm Wafer - Level Chip - Scale Packaging (WLCSP); providing excellent thermal conductivity, small footprint, and low electrical resistance for wider application usage.
