FPF2025 − Full Functional Load Switch With 100mA Current Limit
The FPF2024/5/6/7 are low RDS(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. Pb-Free 1.0x1.5 mm2 CSP package.
