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-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

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.
