Description
T5&K
&.&2&Z
The FPF2495C 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 (<100 mF). The FPF2495C
consists of a slew−rate controlled low−impedance MOSFET switch
(100 mW maximum) and integrated analog features. The slew−rate
controlled turn−on characteristic prevents inrush current and the
resulting excessive voltage droop on power rails. FPF2495C has
over−voltage protection and over−temperature protection.
The FPF2495C has a True Reverse−Current Blocking (TRCB)

during ON and OFF states. The exceptionally low off−state current
drain (<2 mA maximum) facilitates compliance with standby power
requirements. The input voltage range operates from 2.5 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 /
General−Purpose Input / Output (GPIO) without an external
pull−down resistor.
The device is packaged in advanced, fully “green” compliant,
1.21 mm x 1.21 mm, Wafer−Level Chip−Scale Package (WLCSP).

OPERATION AND APPLICATION DESCRIPTION
Thermal Shutdown
Input Capacitor
To limit the voltage drop on the input supply caused by
transient inrush current when the switch turns on into
discharge load capacitor; a capacitor must be placed in
The thermal shutdown protects the die from internally or
externally generated excessive temperature. During an
over−temperature condition, the switch is turned off. The
switch automatically turns on again if the temperature of the
die drops below the threshold temperature.

can be used to reduce the voltage drop in high−current
applications.
Setting Current Limit
The current limit is set with an external resistor connected

Fault Reporting
Upon the detection of an over−current, OC_FLAGB
signal the fault by activating LOW.
Current Limiting
The current limit ensures that the current through the
switch does not exceed the maximum set value, while not
limiting the minimum value. The current at which the part’s
limit is adjustable through the selection of the external
resistor connected to the ISET pin. Information for selecting
the resistor is found in the section below. The device acts as
a constant−current source when the load draws more than the
maximum value set by the device until thermal shutdown
occurs. The device recovers if the die temperature drops
below the threshold temperature.
Under−Voltage Lockout (UVLO)
Figure 6. Current Limit Settings by RSET (Note 11)
The under−voltage lockout turns the switch off if the input
voltage drops below the lockout threshold. With the ON pin
active, the input voltage rising above the UVLO threshold
releases the lockout and enables the switch.
11. Values based on 1% tolerance resistor.
BOARD LAYOUT
For best performance, all traces should be as short as
possible. To be most effective, the input and output
capacitors should be placed close to the device to minimize
the effect that parasitic trace inductance may have on normal
and short−circuit operation. Using wide traces for VIN,
VOUT, GND helps minimize parasitic electrical effects
along with minimizing the case−to−ambient thermal
impedance.
True Reverse−Current Blocking
The true reverse−current blocking feature protects the
input source against current flow from output to input
regardless of whether the load switch is on or off.
