Description

The FPF1048 advanced load management switch

targets

applications

requiring

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

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.
