General Description
The FPF2000 through FPF2007 is a family of load switches which
provide full protection to systems and loads which may encounter
large current conditions. These devices contain a 0.7 Ω current-limited P-channel MOSFET which can operate over an input voltage
range of 1.8-5.5V. 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 part operates in a constant-current mode to prohibit excessive currents from
causing damage. For the FPF2000-FPF2002 and FPF2004FPF2006, if the constant current condition still persists after 10ms,
these parts will shut off the switch and pull the fault signal pin
(FLAGB) low. The FPF2000, FPF2001, FPF2004 and FPF2005,
have an auto-restart feature which will turn the switch on again
after 80ms if the ON pin is still active. The FPF2002 and FPF2006
do not have this auto-restart feature so the switch will remain off
until the ON pin is cycled. For the FPF2003 and FPF2007, 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 FPF2000 through
FPF2003, the minimum current limit is 50mA while that for the
FPF2004 through FPF2007 is 100mA.
These parts are available in a space-saving 5 pin SC-70 package.

Description of Operation
The FPF2000-FPF2007 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 0.7 Ω
P-channel MOSFET and a controller capable of functioning over
a wide input operating range of 1.8-5.5V. The controller protects
against system malfunctions through current limiting, undervoltage lockout and thermal shutdown. The current limit is preset for either 50mA or 100mA.
On/Off Control
The ON pin controls the state of the switch. Active HI and LO
versions are available. Refer to the Ordering Information for
details. 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 150°C overrides the ON control to turn off the switch. In addition, excessive
currents will cause the switch to turn off in FPF2000-FPF2002
and FPF2004-FPF2007. The FPF2000, FPF2001, FPF2004
and FPF2005 have an Auto-Restart feature which will automatically turn the switch on again after 80ms. For the FPF2002 and
FPF2006, the ON pin must be toggled to turn-on the switch
again. The FPF2003 and FPF2007 do not turn off in response
to a over current condition but instead remain operating in a
constant current mode so long as ON is active and the thermal
shutdown or under-voltage lockout have not activated.
Fault Reporting
Upon the detection of an over-current, an input under-voltage,
or an over-temperature condition, the FLAGB signals the fault
mode by activating LO. For the FPF2000-FPF2002 and
FPF2004-FPF2006, the FLAGB goes LO at the end of the
blanking time while FLAGB goes LO immediately for the
FPF2003 and FPF2007. FLAGB remains LO through the AutoRestart Time for the FPF2000, FPF2001 FPF2004 and
FPF2005. For the FPF2002 and FPF2006, FLAGB is latched
LO and ON must be toggled to release it. With the FPF2003 and
FPF2007, FLAGB is LO during the faults and immediately

returns HI at the end of the fault condition. FLAGB is an opendrain MOSFET which requires a pull-up resistor between V
and FLAGB. During shutdown, the pull-down on FLAGB is disabled to reduce current draw from the supply.
Current Limiting
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 FPF2000-FPF2003 the minimum current is 50mA and the maximum current is 100mA and for the
FPF2004-FPF2007 the minimum current is 100mA and the
maximum current is 200mA. The FPF2000-FPF2002 and the
FPF2004-FPF2006, have a blanking time of 10ms, 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 and
the FLAGB pin will activate to indicate that current limiting has
occurred. The FPF2003 and FPF2007 have no current limit
blanking period so immediately upon a current limit condition
FLAGB is activated. These parts will remain in a constant current state until the ON pin is deactivated or the thermal shutdown turns-off the switch.
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 FLAGB is activated and the switch is
turned-off. The switch automatically turns-on again if temperature of the die drops below the threshold temperature.

When using the FPF2002 and FPF2006 attention must be given
to the manual resetting of the part. Continuously resetting the
part at a high duty cycle when a short on the output is present
can cause the temperature of the part to increase. The junction
temperature will only be allowed 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 FPF2003 and FPF2007, a short on
the output will cause the part to operate in a constant current
state dissipating a worst case power as calculated in (3) until
the thermal shutdown activates. It will then cycle in and out of
thermal shutdown so long as the ON pin is active and the short
is present.
