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  
currentlimited Pchannel MOSFET which can operate over an input  
voltage range of 1.85.5 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 overcurrent  
condition causes excessive heating.  
When the switch current reaches the current limit, the parts operate  
in a constantcurrent 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 autorestart feature which will turn the switch on  
again after 160 ms if the ON pin is still active. The FPF2124 does not  
have this autorestart 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 spacesaving 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 Pchannel MOSFET  
and a controller capable of functioning over a wide input  
operating range of 1.85.5 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 turnedoff. 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  
turnsoff the switch.

undervoltage 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  
UnderVoltage Lockout  
is no fault. For all versions, an undervoltage on V or a  
The undervoltage lockout turnsoff the switch if the  
input voltage drops below the undervoltage lockout  
threshold. With the ON pin active, the input voltage rising  
above the undervoltage lockout threshold will cause a  
controlled turnon of the switch which limits current  
overshoots.  
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 AutoRestart feature which  
will automatically turn the switch on again after 160 ms. For  
the FPF2124, the ON pin must be toggled to turnon 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 undervoltage lockout have not  
activated.  
Thermal Shutdown  
The thermal shutdown protects the die from internally or  
externally generated excessive temperatures. During an  
overtemperature condition the switch is turnedoff. The  
switch automatically turnson again if the temperature of  
the die drops below the threshold temperature.  
The ON pin control voltage and V pin have independent  
IN  
recommended operating ranges. The ON pin voltage can be  
driven by a voltage level higher than the input voltage.

Setting Current Limit  
The FPF2123, FPF2124, and FPF2125 have a current

between ISET and GND. This resistor is selected by using  
the following equation (1),

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 turnon  
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

effects along with minimizing the case to ambient thermal
