General Description
The FPF2140/42/43/44/46/47 is a series of load switches which
provides full protection to systems and loads which may
encounter large current conditions. These devices contain a
0.12current-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 part
operates in a constant-current mode to prohibit excessive
currents from causing damage. For the FPF2140/42/44/46, if
the constant current condition still persists after 30ms, the part
will shut off the switch and pull the fault signal pin (FLAGB) low.
The FPF2140/44 have an auto-restart feature which will turn the
switch on again after 450ms if the ON pin is still active. The
FPF2142/46 do not have this auto-restart feature so the switch
will remain off until the ON pin is cycled. For the FPF2143/47, 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. The minimum
current limit is 200mA for the FPF2140/42/43 while that for the
FPF2144/46/47 is 400mA.
These parts are available in a space-saving 6 pin 2X2 MLP
package.
