General Description
The FPF2163, FPF2164, and FPF2165 is a series of load
switches which provides full protection to systems and loads
which may encounter large current conditions. These devices
contain a 0.12鈩?current-limited P-channel MOSFET which can
operate over an input voltage range of 1.8-5.5V. Internally,
current is prevented 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 parts
operate in a constant-current mode to prohibit excessive
currents from causing damage. For the FPF2163 and FPF2164,
if the constant current condition still persists after 30ms, these
parts will shut off the switch and pull the fault signal pin (FLAGB)
low. The FPF2163 has an auto-restart feature which will turn the
switch on again after 450ms if the ON pin is still active. The
FPF2164 does not have this auto-restart feature so the switch
will remain off until the ON pin is cycled. The FPF2165 will not
turn off after a current limit fault, but will rather remain in the
constant current mode indefinitely. The minimum current limit is
150mA.
These parts are available in a space-saving 6 pin 2X2 MLP
package.
