General Description
The FPF2174 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 and a zener clamp at the
output. 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

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 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.
