FPF2024 ON Semiconductor

FPF2024/25/26/27 Full Function Load Switch with 100 mA Current Limit April 2016 FPF2024/25/26/27 Full Functional Load Switch with 100 mA Current Limit Description Features The FPF2024/5/6/7 are low R P-Channel MOSFET DS(ON) 1.6 V to 5.5 V Input Voltage Range load switches with 150 mA typical current limit value Ultra Low Average Quiescent Current 1 A targeting small package load switch applications. The Typical at1.8 V extended input voltage range spans from 1.6 V to 5.5 V to fulfill today s ultra-portable device s supply Typical R = 225 m at V = 3.3 V DS(ON) IN requirements. Switch control is by a logic input (ON) Typical R = 280 m at V = 1.8 V DS(ON) IN capable of interfacing directly with a low voltage control signal. 100 mA Fixed Current Limit Minimum The FPF2024/25/26/27 respond to an output overload Under-Voltage Lockout (UVLO) condition by going into constant current mode where the CMOS and Open Drain Fault Flag Options output current is regulated by the load switch. If the over-current condition persists beyond the 10 ms Fault Blanking Blanking Time, the FPF2024 and FPF2025 pull the fault Auto Restart signal pin (FLAGB) low and shut-off the switch. An Auto- Restart feature turns the FPF2024 and FPF2025 on Thermal Shutdown again after 70 ms if the ON pin is still active. The ESD Protection FPF2026 has a Latch-Off feature which shuts off the switch off after the expiration of the 10 ms Blanking o >5500 V HBM Time and keeps it off until the ON pin is toggled. The o >1500 V CDM 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 Applications overload condition is removed. The FPF2027 has a Startup Blanking feature which prevents startup PDAs transient over-current conditions from triggering the fault Cell Phones signal pin for 10 ms after initial turn on via the ON pin.
