Overview
The FPF1320UCX, produced by onsemi, is a Dual-Input Single-Output (DISO) advanced power switch that integrates two sets of slew-rate controlled, low on-resistance, P-channel MOSFET switches. This device is part of the IntelliMAX™ family and is designed to manage power source transitions seamlessly between two input power rails. It features advanced break-before-make operation and true reverse-current blocking (TRCB) to prevent unwanted current flow from the output to the input. The FPF1320UCX is suitable for low-voltage portable devices and is available in a compact 1.0 mm x 1.5 mm Wafer-Level Chip-Scale Package (WLCSP) with 6 bumps and a 0.5 mm pitch.
