FPF2123-FPF2125
Description
The FPF2123, FPF2124, and FPF2125 are a series of load switches
which provide full protection to systems and loads which may
encounter large current conditions. These devices contain a 0.125 W
current−limited P−channel MOSFET which can operate over an input
voltage range of 1.8−5.5 V. The current limit is settable using
an external resistor. Internally, current is prevented from flowing
when the MOSFET is off and the output voltage is higher than the
input voltage. 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.
When the switch current reaches the current limit, the parts operate
in a constant−current mode to prohibit excessive currents from
causing damage. For the FPF2123 and FPF2124 if the constant current
condition still persists after 10 ms, these parts will shut off the switch.
The FPF2123 has an auto−restart feature which will turn the switch on
again after 160 ms if the ON pin is still active. The FPF2124 does not
have this auto−restart feature so the switch will remain off after
a current limit fault until the ON pin is cycled. The FPF2125 will not
turn off after a current limit fault, but will rather remain in the constant
current mode indefinitely. The minimum current limit is 150 mA.
These parts are available in a space−saving 5 pin SOT23 package.

Description of Operation
Current Limiting
The FPF2123, FPF2124, and FPF2125 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 0.125 W P−channel MOSFET
and a controller capable of functioning over a wide input
operating range of 1.8−5.5 V. The controller protects against
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. 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. The
FPF2123 and FPF2124 have a blanking time of 10 ms,
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. The FPF2125 has no current limit
blanking period so it will remain in a constant current state
until the ON pin is deactivated or the thermal shutdown
turns−off the switch.

under−voltage lockout and thermal shutdown. The current
limit is adjustable from 150 mA to 1.5 A through the
selection of an external resistor.
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 V or a
The under−voltage lockout turns−off the switch if the

above the under−voltage lockout threshold will cause a

IN
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 FPF2123 and
FPF2124. The FPF2123 has an Auto−Restart feature which
will automatically turn the switch on again after 160 ms. For
the FPF2124, the ON pin must be toggled to turn−on the
switch again. The FPF2125 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.
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.

The FPF2123, FPF2124, and FPF2125 have a current

output is present will cause the temperature of the part to
increase. 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
FPF2125, a short on the output will cause the part to operate
in a constant current state dissipating a worst case power of,
During normal operation as a switch, the power dissipated
in the part will depend upon the level at which the current
limit is set. The maximum allowed setting for the current
limit is 1.5 A and this will result in a typical power
dissipation of,

If the part goes into current limit the maximum power
dissipation will occur when the output is shorted to ground.
For the FPF2123 the power dissipation will scale by the

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.

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

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. When using the
FPF2124, attention must be given to the manual resetting of
the part. Continuously resetting the part when a short on the
