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 V to 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 AutoRestart 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 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.
