Overview
The FPF2895CUCX, produced by onsemi, is a highly integrated power switch designed to provide robust protection and efficient power management. This component features a 28 V and 5 A rated current limit power switch, incorporating Over-Current Protection (OCP), Over-Voltage Protection (OVP), and True Reverse Current Block (TRCB) to ensure system reliability. It operates over an input voltage range of 4 V to 22 V and has a low On-resistance of typical 27 mΩ at 5V and 25 °C. The device is packaged in a 24-bump, 1.67 mm x 2.60 mm Wafer-Level Chip-Scale Package (WL-CSP) with a 0.4 mm pitch.
