General Description

The FPF2100 through FPF2107 is a family of load switches

which provide full protection to systems and loads which may

encounter large current conditions. These devices contain a

0.125Ω 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 FPF2100-FPF2102 and

FPF2104-FPF2106, 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 FPF2100, FPF2101,

FPF2104 and FPF2105, have an auto-restart feature which will

turn the switch on again after 160ms if the ON pin is still active.

The FPF2102 and FPF2106 do not have this auto-restart

feature so the switch will remain off until the ON pin is cycled.

For the FPF2103 and FPF2107, 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 FPF2100 through FPF2103, the

minimum current limit is 200mA while that for the FPF2104

through FPF2107 is 400mA.

These parts are available in a space-saving 5 pin SOT23

package.
