This document introduces the features of the FPF2500-FPF2506 series of products, including input voltage range, controlled turn-on, 0.4A, 0.8A and adjustable current limit options, undervoltage lockout, thermal shutdown, <10uA shutdown current, auto restart and fault blanking
The FPF2500‑FPF2506 family are load‑switch ICs that operate from 4.5 V to 20 V input and include features such as controlled turn‑on, thermal shutdown, auto‑restart, and fault‑blanking. Current‑limit options range from 0.5 A to 2 A (adjustable on some parts) and the devices protect against over‑current, undervoltage, and over‑temperature conditions.
The parts are supplied in a 5‑pin SOT‑23 package and are intended for applications such as PDAs, motor drivers, cell phones, and digital cameras. The datasheet details pin functions, absolute maximum ratings, typical characteristics, and dimensional outlines, providing designers with the data needed to integrate the switches into their circuits.
