Overview
The FPF1504BUCX is a low-RDS P-channel MOSFET load switch from the IntelliMAX™ family, manufactured by onsemi. This component is designed to manage power distribution efficiently, particularly in mobile and other low-voltage applications. It features integrated slew-rate control to prevent excessive inrush current, which is common in capacitive loads. The switch also includes an output discharge capability, enhancing its functionality in various power management scenarios.
The device operates within an input voltage range of 1.0 V to 3.6 V, making it suitable for modern mobile devices and other low-voltage systems. The control is managed through a logic input (ON pin) that can interface directly with low-voltage CMOS control signals and GPIOs in embedded processors.
