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 0.7

Ω current-

limited 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 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 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

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. 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.
