General Description
The FPF2000 through FPF2007 is a family of load switches which
provide full protection to systems and loads which may encounter
large current conditions. These devices contain a 0.7Ω current-lim-
ited P-channel MOSFET which can operate over an input voltage
range of 1.8-5.5V. Switch control is by a logic input (ON) capable of
interfacing directly with low voltage control signals. Each part con-
tains thermal shutdown protection which shuts off the switch to pre-
vent damage to the part when a continuous over-current condition
causes excessive heating.
When the switch current reaches the current limit, the part oper-
ates in a constant-current mode to prohibit excessive currents from
causing damage. For the FPF2000-FPF2002 and FPF2004-
FPF2006, 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 FPF2000, FPF2001, FPF2004 and FPF2005,
have an auto-restart feature which will turn the switch on again
after 80ms if the ON pin is still active. The FPF2002 and FPF2006
do not have this auto-restart feature so the switch will remain off
until the ON pin is cycled. For the FPF2003 and FPF2007, a cur-
rent 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. For the FPF2000 through
FPF2003, the minimum current limit is 50mA while that for the
FPF2004 through FPF2007 is 100mA.
These parts are available in a space-saving 5 pin SC-70 package.
