General Description
The FPF2500 through FPF2506 is a family of load switches
which provide full protection to systems and loads which may
encounter large current conditions. These devices contain a
0.23current-limited N-channel MOSFET which can operate
over an input voltage range of 4.5-20V. 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 FPF2500, FPF2501,
FPF2503 and FPF2505, if the constant current condition still
persists after 5ms, these parts will shut off the switch and, for
the FPF2503 and FPF2505, the fault signal pin (FLAGB) will be
pulled low. The FPF2500, FPF2503, and FPF2505, have an
auto-restart feature which will turn the switch on again after
640ms if the ON pin is still active. The FPF2501 does not have
this auto-restart feature so the switch will remain off until the ON
pin is cycled. For the FPF2502, FPF2504 and FPF2506, 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 FPF2500
through FPF2502, the minimum current limit is adjustable from
500mA to 2A. For the FPF2503 and FPF2504 the minimum
current is internally fixed at 400mA while that for the FPF2505
and FPF2506 is internally fixed at 800mA.
These parts are available in a space-saving 5 pin SOT23
package.
