General Description
The FPF2172 is a load switch which combines the functionality
of the IntelliMAX TM series load switch with a very low forward
voltage drop Schottky barrier rectifier. The integrated solution
provides full protection to systems and loads which may
encounter large current conditions in a very compact MLP 3x3
package. This device contain a 0.125 ? current-limited P-
channel MOSFET which can operate over an input voltage
range of 1.8-5.5V. The Schottky diode acts as a barrier so that
no reverse current can flow 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
RoHS Compliant
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. 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 switch will remain off
until the ON pin is cycled. The minimum current limit is 200mA.
These parts are available in a space-saving 6L MLP 3x3
package.
