AP22816AKEWT-7

Overview

The AP22816AKEWT-7 is a single-channel USB power switch IC manufactured by Diodes Incorporated, designed for high-side load switching applications. It operates within a voltage range of 2.7V to 5.5V and supports a maximum continuous output current of 1A. The device features a typical on-resistance of 75 milliohms and utilizes an N/P channel configuration. Packaged in a surface-mount TSOT-25 (SOT-23-5) housing, it integrates comprehensive protection mechanisms including fixed current limiting, overtemperature shutdown, reverse current blocking, short-circuit protection, and under-voltage lockout (UVLO). Additional functional features include load release capabilities and status flag outputs.

Feature Summary

• Integrates fixed current limiting, overtemperature shutdown, reverse current blocking, short-circuit protection, and under-voltage lockout for robust fault management.
• Provides load release functionality and status flag outputs for enhanced system monitoring and control.
• Features a low typical on-resistance of 75 milliohms to minimize power loss during conduction.

Applications

• USB peripheral power switching
• High-side load driver circuits
• Portable electronic device power management

Procurement Notes

Verify the specific suffix 'AKEWT-7' against official Diodes Incorporated documentation to confirm package type, tape-and-reel quantity, and RoHS compliance status. Ensure the ordering part number matches the required marking code and packaging format for automated assembly processes. Cross-reference with the latest datasheet revision to confirm any changes in electrical characteristics or recommended operating conditions prior to final procurement.

Selection Notes

Select this component for applications requiring a single-channel high-side switch with integrated protection features. The 1A current rating and 75 milliohm on-resistance make it suitable for low-power USB loads. Consider the TSOT-25 package size for space-constrained designs. Verify that the input voltage range of 2.7V to 5.5V aligns with the system supply rails and that the non-inverting interface logic is compatible with the control signals.

Part Context

The AP22816AKEWT-7 belongs to the AP2281x series of single-channel, current-limited high-side switches from Diodes Incorporated. This family includes variants such as the AP22817 and AP22818, which share similar architectural features but may differ in current ratings or specific protection thresholds. These devices are categorized under Power Management ICs (PMIC), specifically within the Distribution Switches and Load Drivers subcategory, targeting efficient power distribution in portable electronics.
