AP22654QWU-7

Overview

The AP22654QWU-7 is a precision USB power switch manufactured by Diodes Incorporated, designed for power distribution applications. It features a single output channel with a maximum continuous output current of 3.1 A and a precise current limit of 3.5 A. The device operates within a supply voltage range of 3 V to 5.5 V and exhibits a maximum on-resistance of 75 mOhms. It supports surface mount installation in a TSOT-26 package and functions reliably across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Precision current limiting capability ensures accurate protection against overcurrent conditions
• Low on-resistance design minimizes power loss and heat generation during operation
• Integrated thermal shutdown circuitry protects the component from damage under fault conditions

Applications

• USB port power switching and distribution
• Power management in portable electronic devices
• Battery-powered equipment requiring efficient load switching

Procurement Notes

Verify the specific manufacturer part number AP22654QWU-7 against official Diodes Incorporated documentation to confirm exact electrical specifications and package details. Ensure that the procurement source provides valid RoHS compliance information and authentic datasheets. Cross-reference the ordering suffix to guarantee the correct tape and reel quantity and packaging configuration required for your manufacturing process.

Selection Notes

Select this component when a high-current single-channel switch with precise current limiting is required for USB or similar bus architectures. The wide operating temperature range makes it suitable for industrial or automotive environments where thermal stability is critical. Consider the low on-resistance for efficiency-sensitive designs and verify that the TSOT-26 package fits the available PCB footprint constraints.

Part Context

This component belongs to the AP2265x series of power switches from Diodes Incorporated, which are optimized for power distribution tasks. The series includes variants with different current ratings and packages, such as the AP22653 and AP22655. The AP22654 specifically balances higher current capacity with precision control, fitting into the broader portfolio of load switches and power distribution ICs offered by the manufacturer.

Replacement Considerations

The AP22655QWU-7 is a confirmed substitute within the same family, offering identical package and voltage specifications but potentially differing in current rating parameters. Verify functional compatibility before substitution.
