FAIRCHILD FPF1048BUCX

FPF1048
IntelliMAX™ 3 A-Capable, Slew-Rate-Controlled Load Switch
with True Reverse Current Blocking
Features
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 lowimpedance 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.
Input Voltage Operating Range: 1.5 V to 5.5 V
Typical RDS(ON):
-
21 mΩ at VIN=5.5 V
-
23 mΩ at VIN=4.5 V
-
41 mΩ at VIN=1.8 V
-
90 mΩ at VIN=1.5 V

3 A Maximum Continuous Current Capability
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.
Low Off Switch Current: <1 µA
