ON FPF1039UCX

通用1不需要3.5A

Overview

The FPF1039UCX advanced load management switch targets 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 FPF1039UCX 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 facilitate compliance in very low standby power applications. The input voltage range operates from 1.2 V to 5.5 V DC to fulfill 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" 1 mm x 1.5 mm Wafer-Level Chip-Scale Packaging (WLCSP); providing excellent thermal conductivity, small footprint, and low electrical resistance for wider application usage.
