Description of Operation
The FPF2116 is a current limited switch that protects systems
and loads which can be damaged or disrupted by the
application of high currents. The core of the device is a 0.125 ?
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 200mA.
On/Off Control
The ON pin controls the state of the switch. Activating ON
continuously holds the switch in the on state so long as there is
no fault. An under-voltage on V IN or a junction temperature in
excess of 150°C overrides the ON control to turn off the switch.
In addition, excessive current will cause the switch to turn off.
The part has an Auto-Restart feature which will automatically
turn the switch on again after 480 ms. ON is active HI and has a
low threshold making it capable of interfacing with low voltage
signals. When the MOSFET is off, the body diode is disabled so
no current can flow through it.
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 immediately activating LO. The FLAGB goes LO at the
end of the blanking time. It will remain LO during the fault 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 400mA while not limiting at less than 200mA.
The part has a blanking time of 30 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 and the FLAGB pin
will activate to indicate that current limiting has occurred.
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 part 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.
