AP22817BKCWT-7

Overview

The AP22817BKCWT-7 is a USB power switch IC manufactured by Diodes Incorporated, designed for managing power delivery in USB applications. It features a P-channel configuration with a 1:1 ratio and supports an operating voltage range of 2.7V to 5.5V. The device provides a continuous current capacity of 1.5A and includes integrated protection mechanisms such as fixed current limiting, overtemperature shutdown, reverse current blocking, short-circuit protection, and under-voltage lockout (UVLO). It utilizes a TSOT-23-5 surface-mount package.

Feature Summary

• Integrated P-channel power switch for USB power management
• Built-in protection against overcurrent, overheating, and reverse current
• Supports standard USB voltage ranges with low on-resistance
• Compact surface-mount packaging for space-constrained designs

Applications

• USB port power switching and control
• Portable electronic device power distribution
• Consumer electronics power management systems
• Industrial equipment USB interface protection

Procurement Notes

Verify the exact suffix 'BKCWT-7' against the manufacturer's official datasheet to confirm pinout and electrical specifications. Ensure compatibility with your PCB footprint, specifically the TSOT-23-5 package dimensions. Confirm that the 1.5A current rating meets your application requirements. Check for any recent product change notifications or obsolescence notices from Diodes Incorporated before finalizing procurement.

Selection Notes

Select this component when a compact, protected USB power switch is required. The 1.5A rating suits most standard USB peripherals. Consider the TSOT-23-5 package if board space is limited. Verify thermal performance under load conditions. Compare with similar models like the AP22818 series if higher current or different channel configurations are needed.

Part Context

This part belongs to the AP2281x family of USB power switches from Diodes Incorporated. These devices are designed for high-reliability applications in computing, consumer electronics, and industrial markets. The family offers various current ratings and package options to suit different design constraints while maintaining consistent protection features.

Replacement Considerations

Check for direct substitutes within the AP2281x family, such as AP22817BKAWT-7 or AP22817BKBWT-7, ensuring pin compatibility. Verify that alternative parts meet the same 1.5A current and 2.7V-5.5V voltage requirements. Cross-reference package types to ensure mechanical fit.
