AP2501FGE-7

Power Distribution Switches, Load Drivers Overview

The AP2501FGE-7 is a single-channel, high-side power switch IC manufactured by Diodes Incorporated. It utilizes a P-channel MOSFET to manage power distribution with a continuous output current capability of 2.5A and a typical on-resistance of 70 milliohms. The device operates within a supply voltage range of 2.7V to 5.5V and features fixed current limiting, thermal shutdown, reverse current protection, and under-voltage lockout. Packaged in a compact U-DFN2020-6 surface-mount footprint, it supports an operating temperature range from -40°C to +85°C.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates comprehensive fault protection including fixed current limiting, thermal shutdown, reverse current blocking, and under-voltage lockout for robust system reliability.
• Provides low on-resistance conduction to minimize power loss and heat generation during normal operation.
• Features status flag output to indicate operational state or fault conditions without requiring additional monitoring circuitry.

Power Distribution Switches, Load Drivers Applications

• USB port power switching and overcurrent protection
• Peripheral power distribution in consumer electronics
• Battery-powered device load management

Power Distribution Switches, Load Drivers Procurement Notes

Verify component authenticity through authorized channels as the AP2501 series has received End-of-Life notifications. Confirm specific package availability and lead times directly with the manufacturer or certified distributors. Ensure compliance with RoHS3 standards and check for any product change notices affecting assembly sites or materials before finalizing procurement plans.

Power Distribution Switches, Load Drivers Selection Notes

Select this component for applications requiring a single-channel high-side switch with integrated protection features. The U-DFN2020-6 package suits space-constrained designs. Verify that the required load current does not exceed the 2.5A rating and that the input voltage remains within the 2.7V to 5.5V operational window. Consider thermal performance based on the PCB copper area available for heat dissipation.

Power Distribution Switches, Load Drivers Part Context

The AP2501 belongs to the AP25xx family of single-channel current-limited power switches designed for USB and general power distribution. It serves as a protective element between the power source and the load, replacing discrete MOSFETs and protection diodes to simplify schematic design and reduce board space requirements.

Power Distribution Switches, Load Drivers Replacement Considerations

Public documentation confirms the AP2501SN-7 as a related variant within the same family. Verify pin compatibility and package dimensions before substitution. Note that the AP2501 series has received discontinuance notifications; consult official datasheets for approved alternative part numbers.
