Description
The FPF2024/5/6/7 are low RDS(ON) P-Channel MOSFET
load switches with 150 mA typical current limit value
targeting small package load switch applications. The
extended input voltage range spans from 1.6 V to 5.5 V
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 FPF2024/25/26/27 respond to an output overload
condition by going into constant current mode where the
output current is regulated by the load switch. If the
over-current condition persists beyond the 10 ms
Blanking Time, the FPF2024 and FPF2025 pull the fault
signal pin (FLAGB) low and shut-off the switch. An Auto-
Restart feature turns the FPF2024 and FPF2025 on
again after 70 ms 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 10 ms 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. The FPF2027 has a
Startup Blanking feature which prevents startup
transient over-current conditions from triggering the fault
signal pin for 10 ms after initial turn on via the ON pin.
These parts are available in a space-saving 6-ball
advanced. Pb-Free 1.0 x1.5 mm2 CSP package.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
