Overview
The FPF2895UCX, produced by onsemi, is a 28 V / 5 A rated current limit power switch designed to provide comprehensive protection and control for power distribution systems. This component features Over-Current Protection (OCP), Over-Voltage Protection (OVP), and True Reverse Current Block (TRCB), ensuring robust system protection. It operates over a wide input voltage range of 4 V to 22 V and has an ultra-low on-resistance of typically 27 mΩ at 25°C. The device is available in a 24-bump, 1.67 mm x 2.60 mm Wafer-Level Chip-Scale Package (WL-CSP) with a 0.4 mm pitch, making it suitable for compact and high-performance applications.
