AP22818AKEWT-7

Overview

The AP22818AKEWT-7 is a single-channel USB power switch manufactured by Diodes Incorporated, designed for high-side load switching applications. It operates within a supply voltage range of 2.7V to 5.5V and supports a maximum continuous output current of 2A. The device features a typical on-resistance of 75 milliohms and utilizes a TSOT-25 surface-mount package. It includes integrated protection mechanisms such as fixed current limiting, over-temperature shutdown, reverse current blocking, short-circuit protection, and under-voltage lockout (UVLO).

Feature Summary

• Integrates comprehensive fault protection including fixed current limiting, thermal shutdown, and reverse current blocking.
• Provides status flag indication for monitoring switch state and fault conditions.
• Supports controlled load release to manage discharge paths during shutdown events.

Applications

• USB peripheral power distribution and switching
• Portable electronic device power management
• Consumer electronics load control

Procurement Notes

Verify the specific suffix 'AKEWT-7' against the manufacturer's official datasheet to confirm pinout compatibility and functional specifications. Ensure that the required packaging quantity aligns with standard reel sizes. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the production line.

Selection Notes

Select this component when a single-channel high-side switch with 2A capacity and low on-resistance is required. It is suitable for applications needing integrated protection against over-current and thermal faults. Consider the TSOT-25 package size constraints and the 2.7V to 5.5V operating voltage range for system compatibility.
