Features
General Description
„ 4.5 to 20V Input Voltage Range
The FPF2500 through FPF2506 is a family of load switches
which provide full protection to systems and loads which may
encounter large current conditions. These devices contain a
0.23Ω current-limited N-channel MOSFET which can operate
over an input voltage range of 4.5-20V. Switch control is by a
logic input (ON) capable of interfacing directly with low voltage
control signals. Each part contains thermal shutdown protection
which shuts off the switch to prevent damage to the part when a
continuous over-current condition causes excessive heating.
„ Controlled Turn-On
„ 0.4A, 0.8A and Adjustable Current Limit Option
„ Undervoltage Lockout
„ Thermal Shutdown
„ <10uA Shutdown Current
„ Auto Restart
„ Fault Blanking
When the switch current reaches the current limit, the part
operates in a constant-current mode to prohibit excessive
currents from causing damage. For the FPF2500, FPF2501,
FPF2503 and FPF2505, if the constant current condition still
persists after 5ms, these parts will shut off the switch and, for
the FPF2503 and FPF2505, the fault signal pin (FLAGB) will be
pulled low. The FPF2500, FPF2503, and FPF2505, have an
auto-restart feature which will turn the switch on again after
640ms if the ON pin is still active. The FPF2501 does not have
this auto-restart feature so the switch will remain off until the ON
pin is cycled. For the FPF2502, FPF2504 and FPF2506, a
current limit condition will immediately pull the fault signal pin
low and the part will remain in the constant-current mode until
the switch current falls below the current limit. For the FPF2500
through FPF2502, the minimum current limit is adjustable from
500mA to 2A. For the FPF2503 and FPF2504 the minimum
current is internally fixed at 400mA while that for the FPF2505
and FPF2506 is internally fixed at 800mA.

Typical Characteristics
Current Limiting
The FPF2500 - FPF2506 are current limited switches that
protect systems and loads which can be damaged or disrupted
by the application of high currents. The core of each device is a
0.23Ω N-channel MOSFET and a controller capable of
functioning over a wide input operating range of 4.5 V -20 V.
The controller protects against system malfunctions through
current limiting under-voltage lockout and thermal shutdown.
The current limit for FPF2500, FPF2501 and FPF2502 is
adjustable from 500 mA to 2 A through the selection of an
external resistor. The FPF2503 and FPF2504 the minimum
current is internally fixed at 400 mA while that for the FPF2505
and FPF2506 is internally fixed at 800mA.
The current limit ensures that the current through the switch
doesn't exceed a maximum value while not limiting at less than
a minimum value. For the FPF2500, FPF2501 and FPF2502,
the current at which the parts will limit is adjustable through the
selection of an external resistor connected to ISET. Information
for selecting the resistor is found in the Application Info section.
For the FPF2503 and FPF2504 the minimum current is 400mA
and the maximum current is 800mA and for the FPF2505FPF2506 the minimum current is 800mA and the maximum
current is 1600mA. The FPF2500, FPF2501, FPF2503 and
FPF2505 have a blanking time of 5ms, nominally, during which
the switch will act as a constant current source. At the end of
the blanking time, the switch will be turned-off. For FPF2503
and FPF2505, at the end of the blanking time, the switch will be
turned-off and the FLAGB pin will activate to indicate that
current limiting has occurred. The FPF2502, FPF2504 and
FPF2506 have no current limit blanking period so they will
remain in a constant current state. For FPF2504 and FPF2506,
immediately upon a current limit condition FLAGB is activated.
The FPF2502, FPF2504 and FPF2506 devices will remain in
constant current state until the ON pin is cycled or the thermal
shutdown turns-off the switch.
On/Off Control
The ON pin controls the state of the switch. When ON is high,
the switch is in the on state. Activating ON continuously holds
the switch in the on state so long as there is no fault. For all
versions, an under-voltage on VIN or a junction temperature in
excess of 140°C overrides the ON control to turn off the switch.
In addition, excessive currents will cause the switch to turn off in
the FPF2500, FPF2501, FPF2503 and FPF2505. The
FPF2500, FPF2503 and FPF2505 have an Auto-Restart feature
which will automatically turn the switch on again after 640ms.
For the FPF2501, the ON pin must be toggled to turn-on the
switch again. The FPF2502, FPF2504 and FPF2506 does not
turn off in response to an over current condition but instead
remains operating in a constant current mode so long as ON is
active and the thermal shutdown or under-voltage lockout have
not activated.
Under-Voltage Lockout
The under-voltage lockout turns-off the switch if the input
voltage drops below the under-voltage lockout threshold. With
the ON pin active, the input voltage rising above the
under-voltage lockout threshold will cause a controlled turn-on
of the switch which limits current over-shoots.
Thermal Shutdown
The thermal shutdown protects the die from internally or
externally generated excessive temperatures. 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.

Current Limit Various RSET Values
The FPF2500, FPF2501, and FPF2502 have a current limit
which is set with an external resistor connected between ISET
and GND. This resistor is selected by using the following
equation,
( 0.485 × I SET )
(1)
RSET is in Ohms and ISET is in Amps
The following table can also be used to select RSET. A typical
application would be the 0.500A current that is required by a
single USB port. Using the table below an appropriate selection
for the RSET resistor would be 12.4KΩ. This will ensure that the
port load could draw 0.525A, but not more than 0.875A.
Likewise for a dual port system, an RSET of 34.8KΩ would
always deliver at least 1.050A and never more than 1.750A.
Input Capacitor
To limit the voltage drop on the input supply caused by transient
in-rush currents when the switch turns-on into a discharged load
capacitor or a short-circuit, a capacitor needs to be placed
between VIN and GND. A 0.1uF ceramic capacitor, CIN, placed
close to the pins is usually sufficient. Higher values of CIN can
be used to further reduce the voltage drop.

Application Information
Typical Application
Board Layout
A 0.1uF capacitor COUT, should be placed between VOUT and
GND. This capacitor will prevent parasitic board inductances
from forcing VOUT below GND when the switch turns-off. For the
FPF2501, FPF2503 and FPF2505, the total output capacitance
needs to be kept below a maximum value, COUT(max), to prevent
the part from registering an over-current condition and turning
off the switch. The maximum output capacitance can be
determined from the following formula,
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 effects that parasitic
trace inductances may have on normal and short-circuit
operation. Using wide traces for VIN, VOUT and GND will help
minimize parasitic electrical effects along with minimizing the
case to ambient thermal impedance.
I LIM ( min ) × t BLANK ( min )
C OUT ( max ) = ----------------------------------------------------------------V IN
(2)
Power Dissipation
Due to the wide input voltage range that the parts can accept
and the high currents at which the current limit can be set, care
must be taken to prevent excessive power dissipation in the part
from interrupting the switching of power to a load. During normal
operation as a switch, the power dissipated in the part will
depend upon the level at which the current limit is set. For a
0.5A typical load, the power dissipated will typically be,
2
2
P = ( I LIM ) × R DS = ( 0.5 ) × 0.23 = 58mW
(3)
This is well within the thermal capability of the package. The
maximum allowed setting for the current limit is 2A and this will
result in a power dissipation of typically,
2
2
P = ( I LIM ) × R DS = ( 2 ) × 0.23 = 920mW
(4)
This is beyond the normal thermal capability of the package, but
the thermal shutdown within the part will prevent damage by
turning off the switch once the maximum junction temperature
has been reached. If the part goes into current limit the
maximum power dissipation will occur when the output is
shorted to ground. For the FPF2500, FPF2503 and FPF2505
the power dissipation will scale by the Auto-Restart Time,
tRESTART, and the Over Current Blanking Time, tBLANK, so that
the maximum power dissipated is,
t BLANK
P ( max ) = -------------------------------------------------- × V IN ( max ) × I LIM ( max )
t RESTART + t BLANK
5
(5)
= ------------------- × 20 × 2.5 = 388mW
5 + 640
This is more power than the package can dissipate, but the
thermal shutdown of the part will activate to protect the part
from damage due to excessive heating. The junction
temperature will only be able to increase to the thermal
shutdown threshold. Once this temperature has been reached,
toggling ON will not turn-on the switch until the junction
temperature drops. For the FPF2502, FPF2504 and FPF2506,
a short on the output will cause the part to operate in a constant
current state dissipating a worst case power of,
P ( max ) = V IN ( max ) × I LIM ( max ) = 20 × 2.5 = 50W (6)
This large amount of power will activate the thermal shutdown
and the part will cycle in and out of thermal shutdown so long as
the ON pin is active and the short is present.
