General Description
The FPF2024/5/6/7 are low R DS(ON) P-Channel MOSFET load
switches with 150mA typical current limit value targeting small
package load switch applications. The extended input voltage
range spans from 1.6V to 5.5V to fulfill today's Ultra Portable
Device's supply requirements. Switch control is by a logic input
(ON) capable of interfacing directly with a low voltage control
signal.
The FPF2024/5/6/7 respond to an output overload condition by
going into constant current mode where the output current is
regulated by the load switch. If the overcurrent condition
persists beyond the 10ms Blanking Time, FPF2024 and
FPF2025 pull the fault signal pin (FLAGB) low and shut-off the
switch. An Auto-Restart feature turns FPF2024 and FPF2025
on again after 70ms if the ON pin is still active. The FPF2026
has a Latch-Off feature which shuts off the switch off after the
expiration of the 10ms Blanking Time and keeps it off until the
ON pin is toggled. The FPF2027 responds to an overload
condition by immediately pulling the fault signal pin low and the
switch remains in constant current mode until the output
overload condition is removed. FPF2027 has a Startup Blanking
feature which prevents startup transient overcurrent conditions
from triggering the fault signal pin for 10ms after initial turn on
via the ON pin.
These parts are available in a space-saving 6 ball advanced.
