Fairchild FPF2000-FPF2007 IntelliMAX™ Advanced Load Management Products Data Manual
Summary
This is the technical datasheet for the Fairchild Semiconductor FPF2000-FPF2007 IntelliMAX Advanced Load Management Products family. These load switches provide full protection with 0.7Ω current-limited P-channel MOSFET operating from 1.8V to 5.5V input. Features include controlled turn-on, 50mA and 100mA current limit options, under-voltage lockout, thermal shutdown, auto-restart, and fast current limit response. Applications include PDAs, cell phones, GPS devices, MP3 players, and digital cameras. Target users are power management designers and portable electronics engineers requiring compact, protected load switch solutions for battery-powered devices.

Frequently Asked Questions
What is the input voltage range for FPF2000-FPF2007 switches?
1.8 to 5.5 volts.
How do I know if there's a fault like overcurrent?
The FLAGB pin goes low to indicate over-current, under-voltage, or over-temperature.
What is the difference between FPF2000 and FPF2002 models?
FPF2000 has auto-restart after a fault, FPF2002 stays off until the ON pin is cycled.
What package do these load switches come in?
They are available in a space-saving 5-pin SC-70 package.
What happens during a sustained over-current condition?
Thermal protection shuts off the switch to prevent damage from overheating.
