Description
The FPF1048 advanced load management switch
targets applications requiring a highly integrated
solution. It disconnects loads powered from the DC
power rail (<6 V) with stringent off-state current targets
and high load capacitances (up to 100 µF). The
FPF1048 consists of slew-rate controlled low-
impedance MOSFET switch (23 mΩ typical) and
integrated analog features. The slew-rate controlled
turn-on characteristic prevents inrush current and the
resulting excessive voltage droop on power rails.
The FPF1048 has a True Reverse Current Blocking
(TRCB) function that obstructs unwanted reverse
current from VOUT to VIN during both ON and OFF states.
The exceptionally low off-state current drain (<1µA
maximum) facilitates compliance with standby power
requirements. The input voltage range operates from
1.5 V to 5.5 VDC 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 /
General-Purpose Input / Output (GPIO) without an
external pull-down resistor.
The device is packaged in advanced, fully “green”
compliant, 1.0 mm x 1.5 mm, Wafer-Level Chip-Scale
Package (WLCSP) with backside lamination.
