FPF2002

Power Distribution Switches, Load Drivers Overview

The FPF2002 is a single-channel load switch manufactured by onsemi. It integrates an N-channel power MOSFET with integrated input and output capacitors to minimize external component requirements. The device features a low on-resistance and supports input voltages up to 5.5 V. It includes programmable current limit protection and adjustable soft-start functionality to manage inrush current during startup. The switch is controlled via an enable pin and offers reverse current blocking capabilities. It is available in compact packages such as SC-70-6 and UDFN-6, designed for space-constrained portable applications.
