Power Distribution Switches, Load Drivers datasheet and documents for FPF2125

FPF2125

Power Distribution Switches, Load Drivers Overview

The FPF2125 is a single-channel load switch featuring an integrated P-channel MOSFET with adjustable current limiting capabilities. It operates within an input voltage range of 1.8V to 5.5V and supports an adjustable current limit between 0.15A and 1.5A, set via an external resistor. Key electrical parameters include less than 2μA shutdown current, undervoltage lockout, and thermal shutdown protection. The device offers fast current limit response times of 3μs for moderate overcurrents and includes fault blanking and reverse current blocking features.

Power Distribution Switches, Load Drivers Feature Summary

Adjustable current limiting allows customization of protection thresholds using an external resistor
Integrated thermal shutdown prevents damage during continuous over-current conditions
Reverse current blocking prevents backflow when the output voltage exceeds the input

Power Distribution Switches, Load Drivers Applications

Portable digital devices such as PDAs and cell phones
GPS navigation units and MP3 players
Digital cameras and peripheral ports
Hot swap power supply applications

Power Distribution Switches, Load Drivers Procurement Notes
