FPF3380UCX

Power Distribution Switches, Load Drivers Overview

The FPF3380UCX is a single-channel overvoltage protection (OVP) device integrating an N-MOSFET switch and TVS diode. It operates within a 2.8V to 23V input voltage range with a maximum continuous current of 5A. The internal NMOS transistor features a typical on-resistance of 15mΩ. Overvoltage protection triggers at +28V, shutting down the internal FET to safeguard downstream components. An integrated TVS provides ±110V surge protection compliant with IEC61000-4-5. The device includes programmable overvoltage lockout (OVLO), thermal shutdown, and high ESD immunity. It is housed in a compact 12-bump WLCSP package measuring 1.83x1.29mm and supports an operating temperature range from -40°C to +85°C.
