General Description
The FPF2148 is a load switch which provides full protection to systems and loads which may encounter large current conditions. These devices contain a 0.15Ω current-limited P-channel MOSFET which can operate over an input voltage range of 1.8-5.5V. Switch control is by a logic input (ONB) capable of interfacing directly with low voltage control signals. The part contains thermal shutdown protection which shuts off the switch to prevent damage to the part when a continuous over-current condition causes excessive heating.

Features
■ 1.8 to 5.5V Input Voltage Range
■ Controlled Turn-On
■ 200mA Current Limit Options
■ Undervoltage Lockout
■ Thermal Shutdown
■ <2µA Shutdown Current
■ Fast Current limit Response Time
    ■ 5µs to Moderate Over Currents
    ■ 30ns to Hard Shorts
■ Fault Blanking
■ Power Good Function
■ RoHS Compliant

Applications
■ PDAs
■ Cell Phones
■ GPS Devices
■ MP3 Players
■ Digital Cameras
■ Peripheral Ports
■ Hot Swap Supplies
