General Description
The FPF2108-FPF2110 is a series of load switches which
provides full protection to systems and loads which may
encounter large current conditions. This devices contain a
0.125 ? current-limited P-channel MOSFET which can operate
over an input voltage range of 1.8-5.5V. Internally, reverse
current blocking prevents current from flowing 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. For the FPF2108, if the
constant current condition still persists after 10ms, the part will
shut off the switch and pull the fault signal pin (FLAGB) low. The
switch will remain off until the ON pin is cycled. For the
FPF2109 and FPF2110, 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. The minimum current limit is 200mA for the
FPF2109 while that for the FPF2108 and FPF2110 is 400mA.
These parts are available in a space-saving 5 pin SOT23
package .
