FPF2505

FPF2505 Description

The FPF2505 is a high-side power switch from onsemi, part of the IntelliMAX™ series, designed for general-purpose applications. This IC features a 1:1 input-to-output ratio and is housed in a compact SOT23-5 package, making it ideal for space-constrained designs. The device operates within a load voltage range of 4.5V to 20V and offers a maximum output current of 1.2A. It is designed to provide robust fault protection, including fixed current limiting, over-temperature protection, and under-voltage lockout (UVLO). ThePF F2505 also includes an auto-restart feature and a status flag for enhanced system monitoring. With a typical on-state resistance (Rds On) of 230mOhm, this power switch ensures efficient power delivery and minimal power loss. The device is REACH unaffected and has a moisture sensitivity level (MSL) of 1, allowing for unlimited storage and handling. It is available in a surface-mount package and is shipped in tape and reel (TR) format.
