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 ?
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, under-
voltage 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 Auto-
Restart 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 open-
drain MOSFET which requires a pull-up resistor between V IN
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.
Reverse Voltage
If the voltage at the V OUT pin is larger than the V IN pin, large
currents may flow and can cause permanent damage to the
device. FPF2000-FPF2007 is designed to control current flow
from V IN to V OUT .
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.
