AP2281-1FMG-7

Overview

The AP2281-1FMG-7 is a programmable high-side power load switch manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.5V to 6.0V and supports an output current of up to 2A. The device features a maximum on-state resistance of 80mΩ in the U-DFN2018-6 surface-mount package. It includes integrated protection mechanisms such as overcurrent, thermal shutdown, and reverse current blocking. The component is designed for efficient power distribution in portable electronics and industrial systems.

Feature Summary

• Programmable load switching capability with active-high interface control
• Integrated protection against overcurrent, thermal overload, and reverse current flow
• Low on-state resistance for minimized power loss during conduction
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• Portable consumer electronics power management
• Industrial system power distribution
• Peripheral device power switching
• Battery-powered equipment load control

Procurement Notes

Verify the exact suffix FMG corresponds to the U-DFN2018-6 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the ordering part number matches the specific tape-and-reel quantity requirements for your manufacturing line. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Selection Notes

Select this component when a low-profile, high-current load switch is required for 1.5V to 6V systems. The 80mΩ Rds(on) makes it suitable for applications prioritizing efficiency. Consider the U-DFN2018-6 package for board space optimization. Verify that the 2A continuous current rating meets the load requirements. Ensure the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the target application.

Part Context

This part belongs to the AP2281 series of power load switches from Diodes Incorporated. The series offers various configurations including single-channel and dual-channel options with different package types. The AP2281-1FMG-7 specifically denotes the single-channel variant with the FMG suffix indicating the U-DFN2018-6 footprint. This family is designed for general-purpose power distribution in modern electronic devices requiring compact solutions.

Replacement Considerations

Check for direct substitutes within the AP2281 series, such as the AP2281-2FMG-7 for dual-channel needs. Verify pinout compatibility if replacing with other manufacturers' equivalents. Ensure the replacement maintains the 1.5V-6V input range and 2A current capacity. Confirm package dimensions match the U-DFN2018-6 form factor to avoid PCB redesign.
