Description
The FPF1038/39 advanced load-management switches
target applications requiring a highly integrated solution
for disconnecting loads powered from DC power rail
(<6V) with stringent shutdown current targets and high
load capacitances (up to 200µF). The FPF1038/39
consists
MOSFET switch (21mΩ 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.
These devices have exceptionally low shutdown current
drain (<1µA maximum) that facilitates compliance in low
standby power applications. The input voltage range
operates from 1.2V to 5.5V 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
x1.5mm Wafer-Level Chip-Scale Packaging (WLCSP);
providing excellent thermal conductivity, small footprint,
and low electrical resistance for wider application usage.
