FPF2109 Description

Short technical summary and product information.

The FPF2109 is a load switch from ON Semiconductor, part of the IntelliMAX family. It provides robust protection for systems and loads against overcurrent conditions. This device utilizes a P-channel MOSFET with a fixed current limit of 200mA, suitable for applications requiring controlled power delivery.

 

The FPF2109 operates over an input voltage range of 1.8V to 5.5V. It includes essential protection features such as thermal shutdown, reverse current blocking, and undervoltage lockout (UVLO). The switch is controlled via a logic-level ON input, allowing direct interface with low-voltage control signals. Its fault protection includes current limiting, over-temperature protection, reverse current blocking, and UVLO.

 

Packaged in a space-saving SOT-23-5 (SC-74A, SOT-753) surface-mount package, the FPF2109 is designed for applications where board space is limited. Its typical Rds On is 125mOhm, ensuring efficient power transfer. The device is suitable for various portable and consumer electronics, including PDAs, cell phones, and digital cameras, where reliable power management and load protection are critical.
