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 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 (<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
x1.5 mm Wafer-Level Chip-Scale Packaging (WLCSP);
providing excellent thermal conductivity, small footprint,
and low electrical resistance for wider application usage.
