Overview
The FPF2495C, also available in the FPF2495BUCX package, is an advanced load-management switch designed by onsemi. This component is tailored for applications that require a highly integrated solution, particularly those involving DC power rails with stringent off-state current targets and high load capacitances. The FPF2495C features a slew-rate controlled low-impedance MOSFET switch, which helps prevent inrush current and excessive voltage droop on power rails. It also includes integrated analog features, over-voltage protection, and over-temperature protection.
